AD8657 - Micropower CMOS RRIO Operational Amplifier

Description

The AD8657/AD8659 are dual and quad micropower, precision, rail-to-rail input/output amplifiers optimized for low power and wide operating supply voltage range applications.

The AD8657/AD8659 operate from 2.7 V to 18 V with a typical quiescent supply current of 18 μA.

Features

  • Micropower at high voltage (18 V): 22 μA maximum Low offset voltage: 350 μV maximum Low input bias current: 20 pA maximum Gain bandwidth product: 230 kHz at AV = 100 typical Unity-gain crossover: 230 kHz.
  • 3 dB closed-loop bandwidth: 305 kHz Single-supply operation: 2.7 V to 18 V Dual-supply operation: ±1.35 V to ±9 V Unity-gain stable Excellent electromagnetic interference immunity.
