Product Overview

The INA125P is a low power, high accuracy instrumentation amplifier with precision voltage reference in 16pin DIP package. It provides complete bridge excitation and precision differential input amplification on single integrated circuit. A single external resistor sets any gain from 4 to 10000. The INA125P is laser trimmed for low offset voltage, low offset drift and high common mode rejection. The voltage reference is externally adjustable withpin selectable voltages of 1.24V, 2.5V, 5V and 10V for use with variety of transducers. The reference voltage is accurate to ±0.5% (maximum) with ±35ppm/°C drift (maximum). Sleep mode allows shutdown and duty cycle operation to save power.
  • -3db bandwidth of 150KHz at G=4
  • Low quiescent current of 460μA
  • Low offset voltage of ±50μV
  • Low offset drift of ±2mV/°C (maximum)
  • Low input bias current of 10nA
  • High CMR of 114dB at G=500
  • Low noise of 38nV/√Hz at f=1KHz
  • Input protection to ±40V
  • Single supply range from 2.7V to 36V and dual supply range from ±1.35V to ±18V
  • Operating temperature range from -55°C to 125°C
