MicroPower Instrumentation Amplifier, INA122PA, Texas Instruments
The INA122 is a precision instrumentation amplifier for accurate, low-noise differential signal acquisition. The two-op-amp design provides excellent performance with very low quiescent current (60 µA), and is designed for portable instrumentation and data acquisition system. The INA122 can be operated with a single or dual power supply from 2.2 V to 36 V. A single external resistor sets gain from 5 V/V to 10000 V/V. Laser trimming provides very low offset voltage (250 µV maximum), offset voltage drift (3 µV/°C maximum), and excellent common-mode rejection.
