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 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 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 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.

COMPARATOR OPERATION
COMPARATOR, V

OUT

Although op amps are quite different from comparators,
occasionally an unused section of a dual or a quad op amp may
be used as a comparator; however, this is not recommended for
any rail-to-rail output op amp. For rail-to-rail output op amps,
the output stage is generally a ratioed current mirror with bipolar
or MOSFET transistors. With the part operating open loop, the
second stage increases the current drive to the ratioed mirror to
close the loop. However, the second stage cannot close the loop,
which results in an increase in supply current. With the op amp
configured as a comparator, the supply current can be signifi-
cantly higher (see Figure 45). Configuring an unused section as
a voltage follower with the noninverting input connected to a
voltage within the input voltage range is recommended. The
ADA4610-2 has a unique output stage design that reduces the
excess supply current, but does not entirely eliminate this effect
when the op amp is operating open loop.
