data sheet specifications
The AD8608-KGD1 is a single, rail-to-rail input and output,
single-supply amplifier that features very low offset voltage, low
input voltage and current noise, and wide signal bandwidth.
The AD8608-KGD uses the Analog Devices, Inc. patented
DigiTrim® trimming technique, which achieves superior
precision without laser trimming.
APPLICATIONS
Photodiode amplification
Battery-powered instrumentation
Multipole filters
Sensors
Barcode scanners
Audio
The combination of low offsets, low noise, very low input bias
currents, and high speed makes this amplifier useful in a
wide variety of applications. Filters, integrators, photodiode
amplifiers, and high impedance sensors all benefit from the
combination of performance features. Audio and other ac
applications benefit from the wide bandwidth and low
distortion. Applications for this amplifier include optical
control loops, portable and loop-powered instrumentation,
and audio amplification for portable devices.
The AD8608-KGD is specified over the extended industrial
temperature range (−40°C to +125°C).
Additional application and technical information can be found
in the AD8605/AD8606/AD8608 data sheet.
