GENERAL DESCRIPTION

The ADA4610-2 is a dual channel, precision JFET amplifier

that features low input voltage and current noise, offset voltage,

input bias current, and rail-to-rail output.

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 provides superior

accuracy in medical instruments, electronic measurement, and

automated test equipment. Unlike many competitive amplifiers,

the ADA4610-2 maintains fast settling performance with

substantial capacitive loads. Unlike many older JFET amplifiers,

the ADA4610-2 does 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 ADA4610-2a perfect fit 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 a great choice for audio applications.

The ADA4610-2 is specified over the −40°C to +125°C

extended industrial temperature range.

The ADA4610-2 is available in the 8-lead narrow SOIC, 8-lead

MSOP, and 8-lead LFCSP packages.
