The LT
®
1006 is the first precision single supply operational
amplifier. Its design has been optimized for single supply
operation with a full set of specifications at 5V.
Specifications at
±15V
are also provided.
The LT1006 has a low offset voltage of 20µV, drift of
0.2µV/°C, offset current of 120pA, gain of 2.5 million,
common mode rejection of 114dB and power supply
rejection of 126dB.
Although supply current is only 340µA, a novel output
stage can source or sink in excess of 20mA while retaining
high voltage gain. Common mode input range includes
ground to accommodate low ground-referenced inputs
from strain gauges or thermocouples, and output can
swing to within a few millivolts of ground. If a higher
slew rate (in excess of 1V/µs) or micropower operation
(supply current down to 90µA) is required, the operating
currents can be modified by connecting an external
optional resistor to Pin 8.
For similar single supply precision dual and quad op amps,
please see the LT1013/LT1014 data sheet. For micropower
dual and quad op amps, please see the LT1078/LT1079
data sheet.

Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
This parameter is guaranteed by design and is not tested.
Note 3:
Regular operation does not require an external resistor. In order
to program the supply current for low power or high speed operation,
connect an external resistor from Pin 8 to Pin 7 or from Pin 8 to Pin 4,
respectively. Supply current specifications (for R
SET
= 180k) do not include
current in R
SET
.
Note 4:
Optional offset nulling is accomplished with a potentiometer
connected between the trim terminals and the wiper to V
–
. A 10k pot
(providing a null range of
±6mV)
is recommended for minimum drift of
nulled offset voltage with temperature. For increased trim resolution and
accuracy, two fixed resistors can be used in conjunction with a smaller
potentiometer. For example, two 4.7k resistors tied to Pins 1 and 5, with a
500Ω pot in the middle, will have a null range of
±150µV.
