INA146 - Programmable Gain Difference Amplifier

Description

The INA146 is a precision difference amplifier that can be used to accurately attenuate high differential voltages and reject high common-mode voltages for compatibility with common signal processing voltage levels.

High-voltage capability also affords inherent input protection.

Features

  • High common-mode voltage:.
  • 40 V at VS = 5 V.
  • ±100 V at VS = ±15 V.
  • Differential gain = 0.1 V/V TO 100 V/V:.
  • Set with External Resistors.
  • Low quiescent current: 570 µA.
  • Wide supply range:.
  • Single Supply: 4.5 V to 36 V.
  • Dual Supplies: ±2.25 V to ±18 V.
  • Low gain error: 0.025%.
  • High common-mode rejection: 80 dB 2.
