LT6003/LT6004/LT6005
1.6V, 1µA Precision
Rail-to-Rail Input and
Output Op Amps
FEATURES
DESCRIPTION
The LT®6003/LT6004/LT6005 are single/dual/quad op
amps designed to maximize battery life and performance
forportableapplications.Theseamplifiersoperateonsup-
plies 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.
■
Wide Supply Range: 1.6V to 16V
■
Low Supply Current: 1µA/Amplifier Max
■
Low Input Bias Current: 90pA Max
■
Low Input Offset Voltage: 500µV Max
■
Low Input Offset Voltage Drift: 1µV/°C
■
CMRR: 100dB
PSRR: 95dB
■
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 capaci-
tive loads, making the LT6003/LT6004/LT6005 amplifiers
ideal when excellent performance is required in battery
powered applications.

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
4.7μFelectrolyticcapacitorshouldbeused.Whenusingsplit
supplies, the same is true for the negative supply pin.
increase(inthenanoamprange).Inputoffsetvoltageerrors
due to I can be minimized by equalizing the noninverting
B
and inverting source impedances.
Theinputoffsetvoltagechangesdependingonwhichinput
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
commonmoderange(CMRR)istypically160μV,maintain-
ing the precision characteristics of the amplifier.
Rail-to-Rail Characteristics
TheLT6003/LT6004/LT6005arefullyfunctionalforaninput
signal range from the negative supply to the positive sup-
ply. 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,
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
includedintheinputleadssothatcurrentdoesnotbecome
V
, between the negative supply to approximately 0.9V
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.
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 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 amplifier.
The complementary drive generator supplies current to
the output transistors that swing from rail to rail.
TheoutputoftheLT6003/LT6004/LT6005isguaranteedto
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,whensourcingmorethan250μA
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.

Input bias current (I ) is minimized with cancellation

circuitry on both input stages. The cancellation circuitry
remains active when V is more than 300mV from either

off and I is determined by the tail current of Q2 and the
the output is forced below V . If the current is transient
B
and limited to 100mA, no damage will occur.

Figure 3. Circuits for Start-Up Characteristics
Start-Up and Output Saturation Characteristics
Adaptive Filter
Micropower op amps are often not micropower during
start-uporduringoutputsaturation. Thiscanwreakhavoc
on limited current supplies, in the worst case there may
not be enough supply current available to take the system
uptonominalvoltages.UnliketheLT6003/LT6004/LT6005,
when the output saturates, some op amps may draw
excessivecurrentandpulldownthesupplies,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
upsaturatedhigh. Anothercircuitcreatesanegativeoffset
forcing the output to come up saturated low, while the last
circuit brings the output up at 1/2 supply. In all cases, the
supplycurrentiswellcontrolledandisnotexcessivewhen
the output is on either rail.
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 speed-
ing 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.

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
