13 for more information www.linear.com/ltc6258 operation the ltc6258 family input signal range extends beyond the negative and positive power supplies. figure 1 depicts a simplified schematic of the amplifier. the input stage is comprised of two differential amplifiers, a pnp stage q1/ q2 and npn stage q3/q4 that are active over different ranges of common mode input voltage. the pnp stage is active between the negative power supply to approxi - mately 1v below the positive supply. as the input voltage approaches the positive supply , transistor q5 will steer the tail current i 1 to the current mirror q6/q7, activating the npn differential pair and the pnp pair becomes inactive for the remaining input common mode range. also for the input stage, devices q17, q18 and q19 act to cancel the bias current of the pnp input pair. when q1/q2 is active, the current in q16 is controlled to be the same as the current q1/q2. thus, the base current of q16 is normally equal to the base current of the input devices of q1/q2. similar circuitry (not shown) is used to cancel the base current of q3/q4. the buffer and output bias stage uses a special compensation technique to take full advantage of the process technology to drive high capacitive loads. the common emitter topology of q14/q15 enables the output to swing from rail to rail. ltc6258/ltc6259/ltc6260 6258960fa
14 for more information www.linear.com/ltc6258 applications information low supply voltage and low power consumption the ltc6258 family of operational amplifiers can oper - ate with power supply voltages from 1.8v to 5.25v. each amplifier draws 20a. the low supply voltage capability and low supply current are ideal for portable applications. high capacitive load driving capability and wide bandwidth the ltc6258 family is optimized for wide bandwidth low power applications. they have a high gain-bandwidth to power ratio and are unity gain stable. when the load capacitance increases, the increased capacitance at the output pushes the non-dominant pole to lower frequency in the open loop frequency response, worsening the phase and gain margin. the ltc6258 family are designed to directly drive up to 100nf of capacitive load in unity gain configuration (see typical performance characteristics, capacitive load handling). low input referred noise the ltc6258 family provides a low input referred noise of 38nv/ hz at 1khz. the average noise voltage density over a 100khz bandwidth is less than 80nv/ hz . the ltc6258 family is ideal for low noise and low power signal process - ing applications. low input offset v oltage the l tc6258 family has a low offset voltage of 400v, which is essential for precision applications. the offset voltage is trimmed with a proprietary trim algorithm to ensure low offset voltage over the entire common mode voltage range. low input bias current the ltc6258 family uses a bias current cancellation circuit to compensate for the base current of the input transistors. when the input common mode voltage is within 200mv of either rail, the bias cancellation circuit is no longer active. for common mode voltages ranging from 0.2v above the negative supply to 0.2v below the positive supply, the low input bias current allows the amplifiers to be used in applications with high resistance sources. ground sensing and rail to rail output the ltc6258 family delivers over 4ma of output drive current. the output stage is a rail-to-rail topology that is capable of swinging to within 300mv of either rail. if output swing to the negative rail is required, an external pull down resistor to a negative supply can be added. for 5v/0v op amp supplies, a pull down resistor of 10k to C2v will allow a true zero output swing. in this case, the output can swing all the way to the bottom rail while maintaining 45db of open loop gain. since the inputs can go 100mv beyond either rail, the op amp can easily perform true ground sensing. the maximum output current is a function of total supply voltage. as the supply voltage to the amplifier increases, the maximum output current also increases. attention must be paid to keep the junction temperature of the ic below 150c when the output is in continuous short-circuit. the output of the amplifier has reverse-biased diodes con - nected to each supply. the output should not be forced more than 0.5v beyond either supply , other wise current will flow through these diodes. emi rejection electromagnetic interference (emi) rejection is built into the ltc6258 op amp family. rejection is measured by injecting 200mv p-p (C10dbm) rf signal into the pins and measuring the offset change (delta_vos). the rejection ratio is calculated as 20log (100mv/delta_vos). input protection and output overdrive to prevent breakdown of the input transistors, the input stages are protected against a large differential input voltage by two pairs of back-to-back diodes, d5 to d8. if the differential input voltage exceeds 1.4v, the current in these diodes must be limited to less than 10ma. these amplifiers are not intended for open loop applications such as comparators. when the output stage is overdriven, internal limiting circuitry is activated to improve overdrive recovery. in some applications, this circuitry may draw as much as 1ma supply current. ltc6258/ltc6259/ltc6260 6258960fa
15 for more information www.linear.com/ltc6258 esd the ltc6258 family has reverse-biased esd protection diodes on all inputs and output as shown in figure 1. supply voltage ramping fast ramping of the supply voltage can cause a current glitch in the internal esd protection circuits. depending on the supply inductance, this could result in a supply volt - age transient that exceeds the maximum rating. a supply voltage ramp time of greater than 1ms is recommended. feedback components care must be taken to ensure that the pole formed by the feedback resistors and the parasitic capacitance at the inverting input does not degrade stability . for example, in a gain of +2 configuration with gain and feedback resis - tors of 100k, a poorly designed circuit board layout with parasitic capacitance of 5pf (part +pc board) at the ampli - fiers inverting input will cause the amplifier to oscillate due to a pole formed at 640khz. an additional capacitor of 4.7pf across the feedback resistor as shown in figure 2 will eliminate any ringing or oscillation. shutdown the single and dual versions have package options with shdn pins that can shut down the amplifier to less than 7a supply current. the shdn pin voltage needs to be within 0.6v of v C for the amplifier to shut down. during shutdown, the output is in a high output impedance state. when left floating, the shdn pin is internally pulled up to the positive supply and the amplifier remains enabled. 100k 100k 4.7pf c par v out v in 6258960 f02 + ? ltc6258 figure 2. figure 3a. 10khz bandpass filter figure 3b. frequency response of 10khz bandpass filter of figure 3a applications information v + v + c1 4.7nf c2 4.7nf r2 21k c3 4.7nf r3 562 ra1 499k 6258 f03a ra2 499k cd1 1f r1 10k r8 10k in out cd2 0.1f u1 lt6259 ? + 5db/div 5db ?45db 6258 f03b active filter the bandpass filter figure 3a is ac-coupled to an input. as a result, ltc6259 input does not place a burden on the previous stage to develop an absolute common mode voltage. a simple resistor divider with ra1 and ra2 provides biasing for the ltc6259 inputs. pegging the op amp inputs to a fixed voltage helps to reduce distortion that might arise with moving common mode. this filter is centered at 10khz. the exact resistance and capacitance values can be tweaked upwards or downwards, depending on whether lowest resistor noise or lowest total supply current is more important. ltc6258/ltc6259/ltc6260 6258960fa

19 for more information www.linear.com/ltc6258 applications information it is interesting to note that the led current depends on the supply in this implementation in as much as the supply feeds through r2 and r3 to create a reference. the supply also figures into the time of the on and off cycle since the supply powers the edge detection and relaxation part of the circuitry. when the supply falls, the led current drops and the cycle time increases. this change of behavior can help in battery powered led blinking applications to predict end of life. the figure shows the sense resistor voltage (red) and the shutdown pin voltage (blue). the shutdown voltage is tied to v c ; the gate drive couples through c2 as already described. components r f and c f may apparently slow edges down greatly. adding this much delay is not essential, but it can help to smooth out any hiccups that occur when the part goes through a startup sequence after the shutdown pin goes inactive. 47s as a time constant is insignificant in the time scale of the blinking (10s or 100s of ms). the 47s is much smaller than any time constant associated with c2 and its resistors. ? + figure 7a. led driver with self-oscillation figure 7b. led blinker circuit ltc6258/ltc6259/ltc6260 6258960fa v g r sense 10 r2 275k r3 15k c1 1nf c2 1f r gate 10k v g r5 1m r8 1m m3 2n7002 6258 f07a r7 470k r9 140k v c u2 ltc6258 r f 100 c f 470nf 5v 50ms/div ?60.0 0 60.0 120.0 v c 180.0 240.0 300.0 ?2.0 ?1.0 0 1.0 2.0 3.0 4.0 r4 51 sense resistor voltage (mv) shutdown pin voltage (v) 6258 f07b m1 2n7002 led d
