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.
