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 current in R

Note 4: Optional offset nulling is accomplished with a potentiometer connected between the trim terminals and the wiper to V (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 500 pot in the middle, will have a null range of ±150µV.
