Production Data Sept. 1996 Rev 2
3 & 5V Octal 8-Bit Voltage Output DAC with Serial Interface
Description
WM5628L and WM5628 are Octal 8-bit digital to analogue converters (DAC) controlled via a serial interface. Each DAC's output voltage range is programmable for either x1 or x 2 its reference input voltage, allowing near rail to rail operation for the x 2 output range. High impedance buffered voltage reference inputs are provided for each group of four DACs. WM5628L operates on a single supply voltage of 3 V while WM5628 operates on 5 V. WM5628/L interfaces to all popular microcontrollers and microprocessors via a three wire serial interface with CMOS compatible, schmitt trigger, digital inputs. An 12 bit command word comprises 3 DAC select bits, an output range selection bit and 8-bits of data. Individual or all DAC outputs are changed using WM5628/L's double buffered DAC registers and the separate LOAD and LDAC inputs. DAC outputs are updated simultaneously by writing a complete set of new values and then pulsing the LDAC input. The DAC outputs are optimised for single supply operation and driving ground referenced loads. An internal power-on-reset function sets the DAC's input codes to zero at power up. Ideal in space critical applications WM5628/L is available in wide-bodied and DIP packages for commercial (0oC to 70oC) and industrial (-40oC to 85o C) temperature ranges.

Absolute Maximum Ratings are stress ratings only. Permanent damage to the device may be caused by continuously operating at or beyond these limits. Device functional operating range limits are given under Recommended Operating Conditions. Guaranteed performance specifications are given under Electrical Characteristics at the test conditions specified. 2. Total Unadjusted Error is the sum of integral linearity error, zero code error and full scale error over the input code range. 3. Differential Nonlinearity (DNL) is the difference between the measured and ideal 1 LSB amplitude change of any two adjacent codes. A guarantee of monotonicity means the output voltage changes in the same direction (or remains constant) as a change in the digital input code. 4. Integral Nonlinearity (INL) is the maximum deviation of the output from the line between zero and full scale (excluding the effects of zero code and full-scale errors). 5. Zero code error is the deviation from zero voltage output when the digital input code is zero. 6. Zero code error temperature coefficient is given by: 6 ZCETC = (ZCE(Tmax - ZCE(Tmin)) /VREF x 10 / (Tmax - Tmin) 7. Zero-code Error Rejection Ratio (ZCE-RR) is measured by varying the VDD voltage, from 4.5 to 5.5 V d.c., and measuring the proportion of this signal imposed on the zero-code output voltage.

8. Full-scale error is the deviation from the ideal full-scale output (VREF - 1LSB) with an output load of 10k 9. Full-Scale Temperature Co-efficient is given by: FSETC = (FSE(Tmax) - FSE(Tmin)) / VREF x 106 / Tmax - T min) 10. Full Scale Error Rejection Ratio (FSE-RR) is measured by varying the VDD voltage from 4.5 to 5.5 V d.c. and measuring the proportion of this signal imposed on the full-scale output voltage 11 Reference feedthrough is measured at a DAC output with an input code = 00 Hex with a VREF input = 1 Vdc + 1 VPP at 10kHz 12. Channel to channel isolation is measured at a DAC output with an input code of one DAC to FF Hex and the code oa all other DACs to oo Hex with a VREF input = 1 Vdc + 1 Vpp at 10kHz 13 Setting time is the time for the output signal to remain within 0.5 LSB of the final measurement value for a digital input code change of 00 Hex to FF Hex. For WM 5628: VDD = 5V, VREF = 2V and range = x 2. For WM5628L: VDD = 3, VREF = 1.25V and range = x 2. 14 Reference bandwidth is the -3dB bandwidth with an input at VREF = 1.25 Vdc =+ 2 Vpp with a digital input code of full-scale.

Functional Description
DAC operation Each of WM5628/L 's eight digital to analogue converters (DACs) are implemented using a single resistor string with 256 taps corresponding to each of the input 8-bit codes. One end of a resistor string is connected to the GND pin and the other end is driven from the output of a reference input buffer. The use of a resistor string guarantees monotonicity of the DAC's output voltage. Linearity depends upon the matching of the resistor string's individual elements and the performance of the output buffer. Two high input impedance voltage reference buffers are provided, each driving four DACs, Each DAC has a voltage output amplifier which is programmable for gains of x1 or x 2 through the serial interface. The DAC output amplifiers feature rail to rail output stages, allowing outputs over the full supply voltage range to be achieved with a x 2 gain setting and a VDD/2 reference voltage input. Used in this way a slight degradation in linearity will occur as the output voltage approaches VDD. A power-on-reset activates at power up resetting the DACs inputs to code 0. Each output voltage is given by: Vout = Vref x CODE/256 x (RNG+1 ) Where: RNG controls the output gains of x 1 and x 2 CODE is the range 0 to 255 Data Interface WM5628/L's eight double buffered DAC inputs allow several ways of controlling the update of each DAC's output. Serial data is input, MSB first, into the DATA input pin Serial Input DAC Address and Output Tables using CLK, LOAD and LDAC control inputs and comprises 3 DAC address bits, an output range (RNG) bit and 8 DAC input bits. With the LOAD pin high data is clocked into the DATA pin on each falling edge of CLK. Any number of data bits may be clocked in, only the last 12 bits are used. When all data bits have been clocked in, a falling edge at the LOAD pin latches the data and RNG bits into the correct 9 bit input latch using the 3 bit DAC address. If the LDAC input pin is low, the second latch at the DAC input is transparent, and the DAC input and RNG bit will be updated on the falling edge of LOAD simultaneously with the input latch, as shown in figure 1. If the LDAC input is high during serial data input, as shown in figure 2, the falling edge of the LOAD input stores the data in the addressed input latch. The falling edge of LDAC updates the second latches from the input latches and hence the DAC outputs.

Functional Description
(continued) Using these inputs individual DACs can be updated using one 12 bit serial input word and the LOAD pin. Using both LOAD and LDAC, all or selected DACs can be updated after an appropriate number of data words have been inputted. Figures 3 &4 illustrate operation with the 8 clock pulses available from some microprocessors. If the data input is interrupted in this way the clock input must be held low during the break in clock pulses. The RNG bit controls the DAC output range. When RNG = 0 the output is between Vref(A,B,C,D) and GND and when RNG = 1 the range is between 2 x Vref (A,B,C,D) and GND.

Functional Description (Continued)
Linearity, offset, and gain error using single end supplies
When an amplifier is operated from a single supply, the voltage offset can still be either positive or negative. With a positive offset, the output voltage changes on the first code change. With a negative offset the output voltage may not change with the first code depending on the magnitude of the offset voltage. The output amplifier, with a negative voltage offset, attempts to drive the output to a negative voltage. However, because the most negative supply rail is GND, the output cannot drive to a negative voltage. So when the output offset voltage is negative, the output voltage remains at ZERO volts until the input code value produces a sufficient output voltage to overcome the inherent negative offset voltage, resulting in the transfer function shown below This negative offset error, not the linearity error, produces this breakpoint. The transfer function would have followed the dotted line if the output buffer could drive to a negative voltage. For a DAC, linearity is measured between ZERO input code ( all inputs 0 ) and full scale code ( all inputs 1 ) after offset and full scale are adjusted out or accounted for in some way. However, single supply operation does not allow for adjustment when the offset is negative due to the breakpoint in the transfer function. So the linearity in the unipolar mode is measured between full scale code and the lowest code which produces a positive output voltage. The code is calculated from the maximum specification for the negative offset.
