AD8659 - Operational Amplifiers

Download the AD8659 datasheet PDF. This datasheet also covers the AD8657 variant, as both devices belong to the same operational amplifiers family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
