AD8610
The AD8610 is specified over the extended industrial
(-40° to +125°C) temperature range. The AD8610
is available in the 8-lead SOIC and the tiny MSOP8
surface mount packages. MSOP8 packaged devices
are available only in Tape-and-Reel.
APPLICATIONS
Photodiode Amplifier
ATE
Instrumentation
Sensors and Controls
Precision filters
High Fidelity Audio
GENERAL DESCRIPTION
The AD8610 is a precision JFET input amplifier
featuring very low offset voltage and drift, very low
input voltage and current noise, very low input bias
current and wide bandwidth. Outputs are stable with
capacitive loads of over 500pF in non-inverting unity
gain. Output swings to within 1.2V of the supplies even
with a 1kohm load, maximizing dynamic range with
limited supply voltages.
Applications for these amplifiers include electronic
instruments, ATE front-end amplification and integrator
circuits, CAT/MRI/Ultrasound medical
instrumentation, photodiode amplification, fast
precision filters and professional quality audio.
