GENERAL DESCRIPTION
The ADA4610-2/ADA4610-4 are precision JFET amplifiers that
feature low input noise voltage, current noise, offset voltage,
input bias current, and rail-to-rail output. The ADA4610-2/
ADA4610-4 are dual and quad amplifiers, respectively.
The combination of low offset, noise, and very low input bias
current makes these amplifiers especially suitable for high
impedance sensor amplification and precise current
measurements using shunts. With excellent dc precision, low
noise, and fast settling time, the ADA4610-2/ADA4610-4
provide superior accuracy in medical instruments, electronic
measurement, and automated test equipment. Unlike many
competitive amplifiers, the ADA4610-2/ADA4610-4 maintain
fast settling performance with substantial capacitive loads.
Unlike many older JFET amplifiers, the ADA4610-2/ADA4610-4
do not suffer from output phase reversal when input voltages
exceed the maximum common-mode voltage range.
The fast slew rate and great stability with capacitive loads make
the ADA4610-2/ADA4610-4 perfect fits for high performance
filters. Low input bias currents, low offset, and low noise result
in a wide dynamic range for photodiode amplifier circuits. Low
noise and distortion, high output current, and excellent speed
make the ADA4610-2/ADA4610-4 great choices for audio
applications.
The ADA4610-2/ADA4610-4 are specified over the −40°C to
+125°C extended industrial temperature range.
The ADA4610-2 is available in 8-lead narrow SOIC, 8-lead
MSOP, a nd 8 -lead LFCSP packages. The ADA4610-4 is available
in a 14-lead narrow SOIC package.
