в—Џ 8-PIN DIP AND SO-8 SURFACE-MOUNT 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 supplies from 2.2V to 36V and quiescent current is a mere
60ВµA. It can also be operated from dual supplies. By …
