INA823 - Wide-Supply Instrumentation Amplifier

General Description

The INA823 is an integrated instrumentation amplifier that offers low power consumption and operates over a wide, single-supply or dual-supply range.

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

Key Features

  • Input overvoltage protection up to ±60 V.
  • Input voltage extends 150 mV below negative supply.
  • Low power supply current: 180 µA (typ).
  • Precision performance:.
  • Low offset voltage: 20 µV (typ), 100 µV (max).
  • Low input bias current: 8nA (max).
  • Common-mode rejection:.
  • 84 dB, G = 1 (min).
  • 104 dB, G = 10 (min).
  • 120 dB, G ≥ 100 (min).
  • Power supply rejection: 100 dB, G = 1 (min).
  • Input voltage no.
