AD8656ARMZ(RevD) Datasheet - Analog Devices

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.
The AD8655/AD8656 provide low noise (2.7 nV/√Hz @ 10 kHz), low THD + N (0.0007%), and high precision performance (250 µV max over VCM) to low voltage applications. The ability to swing rail-to-rail at the input and output enables designers to buffer analog-to-digital converters (ADCs) and other wide dynamic range devices in single-supply systems.

FEATURES
   Low noise: 2.7 nV/√Hz @ 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 applications (AD8656)

APPLICATIONS
   ADC and DAC buffers
   Audio
   Industrial controls
   Precision filters
   Digital scales
