ADA4177 OVP and EMI Protected, Precision, Low-Noise and Bias Current Op Amps

Robust operational amplifier from Analog Devices that integrates input protection against signal excursions

Image of Analog Devices' ADA4177 Precision Op AmpsADI has introduced the industry’s first and most robust operational amplifier that integrates input protection against signal excursions of 32 V beyond the supply rails, and 70-dB of rejection for electro-magnetic interference (EMI) above 1 GHz. The ADA4177-2 dual-channel, precision, low-noise, low-input operational amplifier was designed to address system designers’ needs for a sensor interface amplifier with precision, linearity, and environmental immunity for mission critical process control, defense, aerospace, and motor control applications, as well as multi-channel data acquisition instrumentation designs.

The ADA4177-2 is typically used in designs where the amplifier inputs are exposed to overvoltage and/or EMI, and the need for improved precision or protection in the signal chain is required. The ADA4177-2 integrates input overvoltage protection (OVP) and EMI filters to protect signal integrity while maintaining system precision and linearity.

Features
  • Low offset voltage: 60 µV maximum at 25°C
  • Low offset voltage drift: 0.7 µV/°C maximum
  • Low input bias current: 1.0 nA maximum at 25°C
  • Dual voltage supply operation:
    • Specified at ±5 V to ±15 V
    • Operation from ±2.5 V to ±18 V
