LT6003/LT6004/LT6005  
1.6V, 1µA Precision  
Rail-to-Rail Input and  
Output Op Amps  
FEATURES  
DESCRIPTION  
TheLT®6003/LT6004/LT6005aresingle/dual/quadopamps  
designed to maximize battery life and performance for  
portable applications. These amplifiers operate on sup-  
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  
n
Low Supply Current: 1μA/Amplifier Max  
n
Low Input Bias Current: 90pA Max  
n
Low Input Offset Voltage: 500μV Max  
n
Low Input Offset Voltage Drift: 2μV/°C  
n
CMRR: 100dB  
PSRR: 95dB  
n
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 2μV/°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

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.  
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,whensourcingmorethan250ꢀA  
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  
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

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  
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  
amplifier and comparator functions.

S1, S2 ARE NORMALLY CLOSED (N = LOW). S3 IS NORMALLY OPEN (N = LOW). A1's OUTPUT OFFSET IS STORED ON C1.  
WHEN A READING IS DESIRED, SWITCHES REVERSE STATE, AND A2 ACTS AS A DIFFERENCE AMPLIFIER FROM THE STORED  
OFFSET. NULL PHASE SHOULD BE ASSERTED 200ms OR MORE. A2 SETTLES 50ms AFTER READ PHASE IS ASSERTED, WITH  
WORST CASE ROOM TEMPERATURE DROOP RATE IS 0.8μV/ms DOMINATED BY ANALOG SWITCH LEAKAGE CURRENT.
