GENERAL DESCRIPTION
The ADA4610-1/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
ADA4610-1 is a single amplifier, the ADA4610-2 is a dual
amplifier, and the ADA4610-4 is a quad amplifier.
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 ADA4610-1/ADA4610-2/ADA4610-4 provide
superior accuracy in medical instruments, electronic measurement,
and automated test equipment. Unlike many competitive
amplifiers, the ADA4610-1/ADA4610-2/ADA4610-4 maintain
fast settling performance with substantial capacitive loads. Unlike
many older JFET amplifiers, the ADA4610-1/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 ADA4610-1/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 ADA4610-1/ADA4610-2/ADA4610-4
great choices for audio applications.
The ADA4610-1/ADA4610-2/ADA4610-4 are specified over
the −40°C to +125°C extended industrial temperature range.
The ADA4610-1 is available in an 8-lead SOIC package and in a
5-lead SOT-23 package. The ADA4610-2 is available in 8-lead
SOIC, 8-lead MSOP, and 8-lead LFCSP packages. The ADA4610-4
is available in a 14-lead SOIC package and in a 16-lead LFCSP.
