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 V 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.
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.
