INA129U - Low-Power Instrumentation Amplifiers

Download the INA129U datasheet PDF. This datasheet also covers the INA128 variant, as both devices belong to the same low-power instrumentation amplifiers family and are provided as variant models within a single manufacturer datasheet.

General Description

The INA128 and INA129 (INA12x) are low-power, general-purpose instrumentation amplifiers that offer excellent accuracy.

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

Key Features

  • Low offset voltage: 50 μV, maximum.
  • Low drift: 0.5 μV/°C, maximum.
  • Low input bias current: 5 nA, maximum.
  • Low noise: 8 nV/√Hz, 0.2 μVpp.
  • High CMR: 120 dB, minimum.
  • Bandwidth: 1.3 MHz (G = 1).
  • Inputs protected to ±40 V.
  • Wide supply range: ±2.25 V to ±18 V.
  • Low quiescent current: 700 μA.
  • Packages: 8-pin plastic DIP, SO-8 2.
