AD8655 - Precision CMOS Amplifier

General Description

The AD8655/AD8656 are the industry’s lowest noise, precision CMOS amplifiers.

They leverage the Analog Devices DigiTrim® technology to achieve high dc accuracy.

Key Features

  • Low noise: 2.7 nV/√Hz at f = 10 kHz Low offset voltage: 250 µV max over VCM Offset voltage drift: 0.4 µV/°C typ and 2.3 µV/°C max Bandwidth: 28 MHz Rail-to-rail input/output Unity gain stable 2.7 V to 5.5 V operation.
  • 40°C to +125°C operation Qualified for automotive.
