INA114 - Precision Instrumentation Amplifier

General Description

The INA114 is a low-cost, general-purpose instrumentation amplifier offering excellent accuracy.

The versatile three-op-amp design and small size make this device an excellent choice for a wide range of applications.

A single external resistor sets any gain from 1 to 10,000.

Key Features

  • Low offset voltage: 50µV maximum for high gains.
  • Low drift: 0.3µV/°C maximum for high gains.
  • Low input bias current: 2nA maximum.
  • High common-mode rejection: 115dB minimum.
  • Input over-voltage protection: ±40V.
  • Wide supply range: ±2.25V to ±18V.
  • Packages: PDIP-8 and SOIC-16 2.
