INA122 - Micropower Instrumentation Amplifier

Description

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 (60μA), and is designed for portable instrumentation and data acquisition systems.

Features

  • Low quiescent current: 60μA.
  • Wide power supply range: 2.2V to 36V.
  • Rail-to-rail output swing.
  • Low offset voltage: 250μV maximum.
  • Low offset drift: 3μV/°C maximum.
  • Low noise: 60nV/√Hz.
  • Low input bias current: 25nA maximum.
  • Packages.
  • 4.9mm × 6mm SOIC.
  • 9.81mm × 9.43mm PDIP 2.
