lt6003/lt6004/lt6005 13 600345fd applications information supply voltage the positive supply of the lt6003/lt6004/lt6005 should be bypassed with a small capacitor (about 0.01f) within an inch of the pin. when driving heavy loads, an additional 4.7f electrolytic capacitor should be used. when using split supplies, the same is true for the negative supply pin. rail-to-rail characteristics the lt6003/lt6004/lt6005 are fully functional for an input signal range from the negative supply to the positive sup - ply. figure 1 shows a simplifed schematic of the amplifer. the input stage consists of two differential amplifers, a pnp stage q3/q6 and an npn stage q4/ q5 that are active over different ranges of the input common mode voltage. the pnp stage is active for common mode voltages, v cm , between the negative supply to approximately 0.9v below the positive supply. as v cm moves closer towards the positive supply, the transistor q7 will steer q2s tail current to the current mirror q8/q9, activating the npn differential pair. the pnp pair becomes inactive for the rest of the input common mode voltage range up to the positive supply. the second stage is a folded cascode and current mir - ror that converts the input stage differential signals into a single ended output. capacitor c1 reduces the unity cross frequency and improves the frequency stability without degrading the gain bandwidth of the amplifer. the complementary drive generator supplies current to the output transistors that swing from rail to rail. input input bias current (i b ) is minimized with cancellation circuitry on both input stages. the cancellation circuitry remains active when v cm is more than 300mv from either rail. as v cm approaches v C the cancellation circuitry turns off and i b is determined by the tail current of q2 and the beta of the pnp input transistors. as v cm approaches v + devices in the cancellation circuitry saturate causing i b to increase (in the nanoamp range). input offset voltage errors due to i b can be minimized by equalizing the noninverting and inverting source impedances. the input offset voltage changes depending on which input stage is active; input offset voltage is trimmed on both input stages, and is guaranteed to be 500v max in the pnp stage. by trimming the input offset voltage of both input stages, the input offset voltage shift over the entire common mode range (cmrr) is typically 160v, maintaining the precision characteristics of the amplifer. the input stage of the lt6003/lt6004/lt6005 incorpo - rates phase reversal protection to prevent wrong polarity outputs from occurring when the inputs are driven up to 9v below the negative rail. 600k protective resistors are included in the input leads so that current does not become excessive when the inputs are forced below v C or when a large differential signal is applied. input current should be limited to 10ma when the inputs are driven above the positive rail. output the output of the lt6003/lt6004/lt6005 is guaranteed to swing within 100mv of the positive rail and 50mv of the negative rail with no load, over the industrial temperature range. the lt6003/lt6004/lt6005 can typically source 8ma on a single 5v supply. sourcing current is reduced to 5ma on a single 1.8v supply as noted in the electrical characteristics. however, when sourcing more than 250a with an output load impedance greater than 20k, a 1f capacitor in series with a 2k resistor should be placed from the output to ground to insure stability. the normally reverse-biased substrate diode from the output to v C will cause unlimited currents to fow when the output is forced below v C . if the current is transient and limited to 100ma, no damage will occur.
lt6003/lt6004/lt6005 14 600345fd applications information gain the open-loop gain is almost independent of load when the output is sourcing current. this optimizes performance in single supply applications where the load is returned to ground. the typical performance characteristics curve of open-loop gain for various loads shows the details. start-up and output saturation characteristics micropower op amps are often not micropower during start-up or during output saturation. this can wreak havoc on limited current supplies. in the worst case there may not be enough supply current available to take the system up to nominal voltages. unlike the lt6003/lt6004/lt6005, when the output saturates, some op amps may draw excessive current and pull down the supplies, compromis - ing rail-to-rail performance. figure 2 shows the start-up characteristics of the lt6003/lt6004/lt6005 for three limiting cases. the circuits are shown in figure 3. one circuit creates a positive offset forcing the output to come up saturated high. another circuit creates a negative offset forcing the output to come up saturated low, while the last circuit brings the output up at 1/2 supply. in all cases, the supply current is well controlled and is not excessive when the output is on either rail. adaptive filter the circuit of figure 4 shows the lt6005 applied as a micropower adaptive flter, which automatically adjusts the time constant depending on the signal level. op amp a1 buffers the input onto the rc which has either a 1ms or 20ms time constant depending on the state of switch s1. the signal is then buffered to the output by op amp a2. op amps a3 and a4 are confgured as gain-of-40 difference amplifers, gaining up the difference between the buffered input voltage and the output. when there is no difference, the outputs of a3 and a4 will be near zero. when a positive signal step is applied to the input, the output of a3 rises. when a negative signal step is applied to the input, the output of a4 rises. these voltages are fed to the lt6700-2 comparator which has a built in 400mv reference. if the input step exceeds 10mv, the output of the difference amplifers will exceed 400mv and the comparator output (wired in or gate fashion) falls low. this turns on s1, reducing the time constant and speed - ing up the settling. the overall effect is that the circuit provides slow fltering with fast settling. waveforms for a 100mv input step are shown in the accompanying photo. the fast 1ms time constant is obvious in the output waveform, while the slow time constant is discernible as the slow ramping sections. that the slow time constant is discernible at all is due to delay time in the difference amplifer and comparator functions. figure 2. start-up characteristics supply voltage (v) 0 supply current per amplifier (a) 1.2 4 600345 f02 1.0 0.8 0.6 0.4 0.2 0 10.5 21.5 3 3.5 4.5 2.5 5 output low output high output at v s /2 t a = 25c figure 3. circuits for start-up characteristics ? + 30mv v s output high ? + v s /2 v s 600345 f03 output at v s /2 ? + 30mv v s output low
