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 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 provide low noise (2.7 nV/√Hz @ 10 kHz),

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

(250 μV max over V_CM) 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 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.
