INA122UA ADC Output

INA122UA ADC Output Module

The INA122UA ADC Output Module 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 INA122UA ADC Output Module can be operated with single power supplies from 2.2V to 36V and quiescent current is a mere
60µA. It can also be operated from dual supplies. By
utilizing an input level-shift network, input commonmode 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 (250µV max), offset voltage drift (3µV/°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
