DESCRIPTION
The LT®6003/LT6004/LT6005 are single/dual/quad op amps designed to maximize battery life and performance for portable applications. These amplifi ers operate on sup­plies as low as 1.6V and are fully specifi ed and guaranteed over temperature on 1.8V, 5V and ±8V supplies while only drawing 1μA maximum quiescent current.
The ultralow supply current and low operating voltage are combined with excellent amplifi er specifi cations; input offset voltage of 500μV maximum with a typical drift of only 2μV/°C, input bias current of 90pA maximum, open loop gain of 100,000 and the ability to drive 500pF capaci­tive loads, making the LT6003/LT6004/LT6005 amplifi ers ideal when excellent performance is required in battery powered applications.
The single LT6003 is available in the 5-pin TSOT-23 and tiny 2mm × 2mm DFN packages. The dual LT6004 is available in the 8-pin MSOP and 3mm × 3mm DFN packages. The quad LT6005 is available in the 16-pin TSSOP and 5mm × 3mm DFN packages. These devices are specifi ed over the com­mercial, industrial and automotive temperature ranges.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime.
Note 2: A heat sink may be required to keep the junction temperature below absolute maximum. This depends on the power supply voltage and how many amplifi ers are shorted. The θ DHC packages is with minimal PCB heat spreading metal. Using expanded metal area on all layers of a board reduces this value.

LT6003/LT6004/LT6005
APPLICATIONS INFORMATION
Supply Voltage
The positive supply of the LT6003/LT6004/LT6005 should be bypassed with a small capacitor (about 0.01μF) within an inch of the pin. When driving heavy loads, an additional
4.7μF 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 sup­ply. Figure 1 shows a simplifi ed schematic of the amplifi er. The input stage consists of two differential amplifi ers, 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,
, between the negative supply to approximately 0.9V
V
CM
below the positive supply. As V
moves closer towards
CM
the positive supply, the transistor Q7 will steer Q2’s 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 mir­ror 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 amplifi er. The complementary drive generator supplies current to the output transistors that swing from rail to rail.
Input
Input bias current (I
) is minimized with cancellation
B
circuitry on both input stages. The cancellation circuitry remains active when V rail. As V off and I
approaches V– the cancellation circuitry turns
CM
is determined by the tail current of Q2 and the
B
is more than 300mV from either
CM
beta of the PNP input transistors. As V devices in the cancellation circuitry saturate causing I
approaches V+
CM
B
to increase (in the nanoamp range). Input offset voltage errors due to I
can be minimized by equalizing the noninverting
B
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 500μV 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 160μV, maintain­ing the precision characteristics of the amplifi er.
The input stage of the LT6003/LT6004/LT6005 incorpo­rates 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
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 250A with an output load impedance greater than 20kΩ, a 1μF 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 the output is forced below V
will cause unlimited currents to fl ow when
. If the current is transient
and limited to 100mA, no damage will occur.

APPLICATIONS INFORMATION
LT6003/LT6004/LT6005
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, compromis­ing 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.

Figure 3. Circuits for Start-Up Characteristics
30mV
Adaptive Filter
The circuit of Figure 4 shows the LT6005 applied as a micropower adaptive fi lter, 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 confi gured as gain-of-40 difference amplifi ers, 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 amplifi ers will exceed 400mV and the comparator output (wired in OR gate fashion) falls low. This turns on S1, reducing the time constant and speed­ing up the settling. The overall effect is that the circuit provides “slow fi ltering” 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 amplifi er and comparator functions.

ADAPTIVE FILTER IMPROVES INHERENT TRADE-OFF OF SETTLING TIME VS NOISE FILTERING. SMALL SIGNAL DC STEPS SETTLE WITH A 20ms TIME CONSTANT FOR AN 8Hz NOISE BANDWIDTH. LARGE STEP SIGNALS (>10mV) CAUSE S1 TO TURN ON, SPEEDING UP THE TIME CONSTANT TO 1ms, FOR IMPROVED SETTLING. AS THE OUTPUT SETTLES BACK TO WITHIN 10mV, 51 TURNS OFF AGAIN, RESTORING THE 20ms TIME CONSTANT, FOR IMPROVED FILTERING.
