DESCRIPTION
The INA122 is a precision instrumentation amplifier
for accurate, low noise differential signal acquisition.
Its two-op-amp design provides excellent performance
with very low quiescent current, and is ideal for
portable instrumentation and data acquisition systems.
The INA122 can be operated with single power sup-
plies from 2.2V to 36V and quiescent current is a mere
60
μ
A. It can also be operated from dual supplies. By
utilizing an input level-shift network, input common-
mode range extends to 0.1V below negative rail (single
supply ground).
A single external resistor sets gain from 5V/V to
10000V/V. Laser trimming provides very low offset
voltage (250
μ
V max), offset voltage drift (3
μ
V/
°
C
max) and excellent common-mode rejection.
Package options include 8-pin plastic DIP and SO-8
surface-mount packages. Both are specified for the
–40
°
C to +85
°
C extended industrial temperature range.
