FT1006
Precision, Single Supply
Op Amp
Features
■
Description
The
FT1006
is the first precision single supply operational
amplifier. Its design has been optimised for single supply
operation with a full set of specifications at 5V.
Specifications at
±15V
are also provided.
The
FT1006
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
FT1013/FT1014
data sheet. For micropower
dual and quad op amps, please see the
FT1078/FT1079
data sheet.
