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 at 10 kHz),

low THD + N (0.0007%), and high precision performance

(250 µV max over V

) 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.

The high precision performance of the

AD8655/AD8656

improves

the resolution and dynamic range in low voltage applications.

Audio applications, such as microphone pre-amps and audio

mixing consoles, benefit from the low noise, low distortion, and

high output current capability of the

AD8655/AD8656

to reduce

system level noise performance and maintain audio fidelity. The

high precision and rail-to-rail input and output of the

AD8655/

AD8656

benefit data acquisition, process controls, and PLL

filter applications.

The

AD8655/AD8656

are fully specified over the −40°C to

+125°C temperature range. The

AD8655/AD8656

are available

in Pb-free, 8-lead MSOP and SOIC packages. The

AD8655/

AD8656

are both available for automotive applications.
