Low Voltage Signal Processing
Micropower Active Filters
The LT®6003/LT6004/LT6005 are single/dual/quad op
amps designed to maximize battery life and performance
for portable applications. These amplifiers operate on supplies as low as 1.6V and are fully specified 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 amplifier specifications; input
offset voltage of 500µV maximum with a typical drift of
only 1µV/°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 amplifiers
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 specified 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 amplifiers are shorted. The θJA specfied for the DC, DD and
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 simplified schematic of the amplifier.
The input stage consists of two differential amplifiers, 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,
VCM, between the negative supply to approximately 0.9V
below the positive supply. As VCM moves closer towards
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 amplifier.
The complementary drive generator supplies current to
the output transistors that swing from rail to rail.
Input
Input bias current (IB) is minimized with cancellation
circuitry on both input stages. The cancellation circuitry
remains active when VCM is more than 300mV from either
rail. As VCM approaches V– the cancellation circuitry turns
off and IB is determined by the tail current of Q2 and the
beta of the PNP input transistors. As VCM approaches V+
devices in the cancellation circuitry saturate causing IB to
increase (in the nanoamp range). Input offset voltage errors
due to IB 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 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 amplifier.
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 250μA
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– will cause unlimited currents to flow when
the output is forced below V–. If the current is transient
and limited to 100mA, no damage will occur.

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 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
Adaptive Filter
The circuit of Figure 4 shows the LT6005 applied as a
micropower adaptive filter, 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 configured as gain-of-40
difference amplifiers, 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 amplifiers 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 filtering” with “fast settling”. Waveforms
are shown in the accompanying photo, for a 100mV input
step. 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
amplifier and comparator functions.

WITH LARGE SIGNAL
ADAPTIVE FILTER IMPROVES INHERENT TRADEOFF 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.
