ad5310 data sheet rev. b | page 10 of 16 terminology relative accuracy for the dac, relative accuracy or integral nonlinearity (inl) is a measure of the maximum deviation, in lsbs, from a straight line passing through the endpoints of the dac transfer function. a typical inl vs. code plot is shown in figure 5 . differential nonlinearity differential nonlinearity (dnl) is the difference between the measured change and the ideal 1 lsb change between any two adjacent codes. a specified differential nonlinearity of 1 lsb maximum ensures monotonicit y. this dac is guaranteed mono - tonic by design. a typical dnl vs. code plot is shown i n figure 6 . zero code error zero code error is a measure of the output error when zero code (000 hex ) is loaded to the dac register. ideally , the output should be 0 v. the zero code error is always positive in the ad5310 because the output of the dac cannot go below 0 v. it is due to a combination of the offset errors in the dac and output amplifier. zero code error is expressed in mv. a plot o f zero code error vs. temperature is shown in figure 9 . full - scale error full - scale error is a measure of the output error when full - scale code (3ff hex) is loaded to the dac register. ideally , the output should be v dd ? 1 lsb. full - scale error i s expressed as a percent age of the full - scale range. a pl ot of full - scale error vs. temperature is shown in figure 9 . gain error gain error is a measure of the span error of the dac. it is the deviation in slope of the dac transfer characteristic from the ideal expressed as a percent age of the full - scale range. total unadjusted error tota l unadjusted error (tue) is a measure of the output err or that tak es all the various errors into account. a typical tue vs. code plot is shown in figure 7 . zero code error drift zero code error drift is a measure of the ch ange in zero code error with a change in temperature. it is expressed in v/c. gain error drift gain error drift is a measure of the change in gain error with changes in temperature. it is expressed in (ppm of full - scale range)/ c. digital -to - analog glitc h impulse digital - to - analog glitch impulse is the impulse injected into the analog output when the input code in the dac register changes state. it is normally specified as the area of the glitch in nv - s and is measured when the digital input code is chang ed by 1 lsb at the major carry transition (1ff hex to 200 hex ). see figure 22. digital feedthrough digital feedthrough is a measure of the impulse injected into the analog output of the dac from the digital inputs of the dac but is measured when the dac output is not updated. it is specified in nv - s and is measured with a full - scale code change on the data bus, that is , from all 0s to all 1s and vice versa.
data sheet ad5310 rev. b | page 11 of 16 theory of operation d/a section the ad5310 dac is fabricated on a cmos process. the architecture consists of a string dac followed by an output buff er amplifier. because there is no reference input pin, the power supply (v dd ) acts as the reference. figure 23 shows a block diagram of the dac architecture. figure 23 . dac architecture because the input coding to the dac is straight binary, the i deal output voltage is given by ? ? ? ? ? ? = 1024 d v v dd out where d is the decimal equivalent of the binary code that is loaded to the dac register; it can range from 0 to 1023. figure 24 . resistor string resistor string the resistor string section is shown in figure 24 . it is simply a string of resistors, each of value r. the code loaded to the dac register determines at what node on the string the voltage is tapped off to be fed into the output amplifier. the voltage is tapped off by closing one of the sw itches connecting the string to the amplifier. because it is a string of resistors, it is guaranteed monotonic. output amplifier the output buffer amplifier is capable of generating rail - to - rail voltages on its output , which results in an output range of 0 v to v dd . it is capable of driving a load of 2 k ? in parallel with 1000 pf to gnd. the source and sink capabilities of the output amplifier can be seen in figure 11 and figure 12 . the slew rate is 1 v/ s with a half - scale settling time of 6 s with the output loaded . serial interface the ad5310 has a 3 - wire serial interface ( sync , sclk , and din) that is compatible with spi, qspi , and microwire interface standards , as well as most dsps. see figure 2 for a timing diagram of a typical write sequence. the write sequence begins by bringing the sync line low. data from the di n line is clocked into the 16 - bit shift register on the falling edge of sclk. the serial clock frequency can be as high as 30 mhz , making the ad5310 compatible with high speed dsps. on the 16th falling clock edge, the last data bit is clocked in and the pr ogrammed function is executed ( that is , a change in dac register contents and/or a change in the mode of operation). at this stage, the sync line can be kept low or be brought high. in either case, it must be brought high for a minimum of 33 ns before the next write sequence so that a falling edge of sync can initiate the next write sequence. because the sync buffer draws more current when v in = 2.4 v than it does when v in = 0.8 v, sync should be idled low between write sequences for even lower power operation of the part. as previously mentioned, however, it must be brought high again just before the next write sequence. input shift register the input shift register is 16 bits wide (see figure 25 ). the first two bits are dont cares. the next two bits are control bits that control which mode of operation t he part is in (normal mode or one of the three power - down modes). there is a more complete description of the various modes in the power - down modes section. the next 1 0 bits are the data bits. these are transferred to the dac register on the 16th falling edge of sclk. finally, the last two bits are dont cares. figure 25 . input register contents
ad5310 data sheet rev. b | page 12 of 16 sync interrupt in a normal write sequence, the sync line is kept low for at least 16 falling edges of sclk , and the dac is updated on the 16th falling edge. however, if sync is brought high before the 16th falling edge , this acts as an interrupt to the write sequence. the shift register is reset , and the write sequence is seen as invalid. neither an update of the dac register contents or a change in the operating mode occurs ( see figure 28) . power - on reset the ad5310 contains a power - on reset circuit that controls the output voltage during powe r - up. the dac register is filled with 0 s, and the output voltage is 0 v. it remains there until a valid write sequence is performed to the dac. this is useful in applications where it is important to know the state of the output of the dac while it is in t he process of powering up. power - down modes the ad5310 contains four separate modes of operation. these modes are software programmable by setting two bits (db13 and db12) in the control register. table 5 shows how the state of the bits corresponds to the mode of operation of the device. table 5 . modes of operation for the ad5310 operating mode db13 db 12 normal operation 0 0 power - down modes 1 k to gnd 0 1 100 k to gnd 1 0 three - state 1 1 when both bits are set to 0, the part works normally with its normal power consumption of 140 a at 5 v. however, for the three power - down modes, the supply current falls to 200 na at 5 v (50 na at 3 v). not only does the supply current fall , but the output stage is also internally switched from the output of the amplifier to a resistor network of k nown values. this has the advantage of knowing the output impedance of the part when the part is in power - down mode. there are three options. the output is connected internally to gnd through a 1 k ? resistor, a 100 k ? resistor , or it is left open - circuited ( three - state ). the output stage is illustrated in figure 26. figure 26 . output stage during power - down the bias generator, the output ampl ifier, the resistor string , and other associated linear circuitry are all shut down when the power - down mode is activated. however, the contents of the dac register are unaffected when in power - down. the time to exit power - down is typically 2.5 s for v dd = 5 v and 5 s for v dd = 3 v (s ee figure 21) . microprocessor inter facing ad5310 to adsp - 2101 interface figure 27 shows a serial interface between the ad5310 a n d the adsp - 2101 . the adsp - 2101 should be set up to operate in the sport transmit alternate framing mode . the adsp - 2101sport is programmed through the sport cont rol register and should be configured as follows: internal clock operation, active low framing, 16 - bit word length. transmission is initiated by writing a word to the tx register after the sport has been enabled. figure 27 . ad5310 to adsp - 2101 interface figure 28 . sync interrupt facility adsp-2101* ad5310* *additiona l pins omitted for clarit y tfs dt sclk sync din sclk
data sheet ad5310 rev. b | page 13 of 16 ad5310 to 68hc11/68l11 interface figure 29 shows a serial interface between the ad5310 and the 68hc11/68l11 microcontroller. sck of the 68hc11/68l11 drives the sclk of the ad5310 , while the mosi output drives the serial data line of the dac. the sync signal is derived from a port line (pc7). the setup conditions for correct operation of this interface are as follows: the 68hc11/68l11 should be configured so that its cpol bit is a 0 and its cpha bit is a 1. when data is being transmitted to the dac, the sync line is taken low (pc7). with th is 68hc11/68l11 configur ation , data appearing on the mosi output is valid on the falling edge of sck. serial data from the 68hc11/68l11 is transmitted in 8 - bit bytes with only eight falling clock edges occurri ng in the transmit cycle. data is transmitted msb first. t o load data to the ad5310 , pc7 is left low after the first eight bits are transferred, a second serial write operation is performed to the dac , and pc7 i s taken high at the end of this procedure. figure 29 . ad5310 to 68hc11/68l11 interface ad5310 to 80c51/80l51 interface figure 30 shows a serial interface between the ad5310 and the 80c51/80l51 microcontroller. the setup for the interface is as follows: txd of the 80c51/80l51 drives sclk of the ad5310 while rxd drives the serial data line of the part. the sync sig nal is again derived from a bit - programmable pin on the port. in this case , port line p3.3 is used. when data is to be transmitted to the ad5310 , p3.3 is taken low. the 80c51/80l51 transmits data only in 8 - bit b ytes; therefore, only eight falling clock edges occur in the transmit cycle. to load data to the dac, p3.3 is left low after the first eight bits are transmitted, and a second write cycle is initiated to transmit the second byte of data. p3.3 is taken high following the completion of this cycle. the 80c51/ 80l51 outputs the serial data in a format that has the lsb first . the ad5310 requires that the msb of data be received first . the 80c51/80l51 transmit routine should take this into account. figure 30 . ad5310 to 80c51/80l51 interface ad5310 to microwire interface figure 31 shows an interface betwe en the ad5310 and any microwire - compatible device. serial data is shifted out on the falling edge of the serial clock and is clocked into the ad5310 on the rising edge of the sk. figure 31 . ad5310 t o microwire in terface
ad5310 data sheet rev. b | page 14 of 16 applicatio ns information using ref19 x as a power supply fo r ad5310 because the supply current required by the ad5310 is extremely low, an alternative option is to use a ref19x voltage reference ( ref195 for 5 v or ref193 for 3 v) to supply the required voltage to the part (s ee figure 32) . this is especially useful if the power supply is quite noisy or if the system supply voltages are at some value other than 5 v or 3 v ( for exa m ple , 15 v). the ref19x output s a steady supply voltage for the ad5310. if the low dropout ref195 is used, the current that it needs to supply to the ad5310 is 140 a. this is with no load on the o utput of the dac. when the dac output is loaded, the ref195 also needs to supply the current to the load. the total current required (with a 5 k ? load on the dac output) is 140 a + (5 v/5 k ? ) = 1.14 ma the loa d regulation of the ref195 is typically 2 ppm/ma , which results in an error of 2.3 ppm (11.5 v) for the 1.14 ma current drawn from it. this corresponds to a 0.002 lsb error. figure 32 . ref195 as power supply to ad5310 bipolar operation us ing the ad5310 the ad5310 is designed for single - supply operation but a bipolar output range is also possible using the circuit shown in figure 33. th is circuit results in an output voltage range of 5 v. rail - to - rail operation at the amplifier o utput is achievable using an ad820 or an op295 as the output amplifier. the output voltage for any input code can be calculated as follows: ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? + ? ? ? ? ? ? = r1 r2 v r1 r2 r1 d v v dd dd o 1024 where d represents the input code in decimal (0 to 1023). with v dd = 5 v, r1 = r2 = 10 k ? , v 5 1024 10 ? ? ? ? ? ? ? = d v o this is an output voltage range of 5 v , with 000 hex corresponding to a ? 5 v output and 3ff hex corresponding to a +5 v output. figure 33 . bipolar operation with the ad5310 using ad5310 with an opto - isolated interface in process control applications in industrial environments , it is often necessary to use an opto - isolat ed interface to protect and isolate the controlling circuitry from any hazardous common - mode voltages that may occur in the area where the dac is functioning. opto - isolators provide isolation in excess of 3 kv. because the ad5310 uses a 3 - wire serial logic interface, it only requires three opto - isolators to provide the required isolation (see figure 34 ). the power supply to t he part also needs to be isolated. this is done by using a transformer. on the dac side of the transformer, a 5 v regulator provides the 5 v supply required for the ad5310 . figure 34 . ad5310 with an opto - isolated interface
data sheet ad5310 rev. b | page 15 of 16 power supply bypassi ng and grounding when accuracy is important in a circuit , it is helpful to carefully consider the power supply and ground return layout on the board. th e printed circuit board containing the ad5310 should have separate analog and digital sections, each having their own area of the board. if the ad5310 is in a system where other devices require an agnd to dgnd connection, the connection should be made at one point only. this ground point should be as close as possible to the ad5310 . the power supply to the ad5310 should be bypassed with 10 f and 0.1 f capacitors. the capacitors should be physically as close as possible to the device , with the 0.1 f capacitor ideally right up against the device. the 10 f capacitors are the tantalum bead type. it is important that the 0.1 f capacitor has low effective series resistance (esr) and effective series inductance (esi), such as is the case with common ceramic types of capacitors. this 0.1 f capacitor provides a low impedance path to ground for high frequencies caused by transient currents due to internal logic switching. the power supply line itself should have as large a trace as possible to provide a low impedance path and to reduce glitch effects on the suppl y line. clocks and other fast switching digital signals should be shielded from other parts of the board by digital ground. avoid crossover of digital and analog signals if possible. when traces cross on opposite sides of the board , ensure that they run at right angles to each other to reduce feedthrough effects through the board. the best board layout technique is the micro - strip technique , where the component side of the board is dedicated to the ground plane only and the signal traces are placed on the s older side. however, this is not always possible with a 2 - layer board.
