CBM8655-CBM8656
OPERATION INSTRUCTION
FEATURES
GENERAL DESCRIPTION
Low noise: 2.7nV/√Hz at f = 10 kHz
The
CBM8655/CBM8656
are
the
industry’s lowest noise, precision CMOS
amplifiers. They leverage the Analog Devices
DigiTrim® technology to achieve high dc
accuracy.
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
The CBM8655/CBM8656 provide low
noise (2.7nV/√Hz at 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.
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
APPLICATIONS
ADC and DAC buffers
Audi
The high precision performance of the
CBM8655/CBM8656 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 CBM8655/CBM8656 to reduce system
level noise performance and maintain audio
fidelity. The high precision and rail-to-rail
input and output of the CBM8655/ CBM8656
benefit data acquisition, process controls, and
PLL filter applications.

The
CBM8655/CBM8656
over the −40°C
are
fully
specified
to+125°C
temperature range. The CBM8655/CBM8656
are available in Pb-free, 8-lead MSOP and
SOIC packages. The CBM8655/CBM8656 are
both available for automotive applications.
