GENERAL DESCRIPTION
The ADA4001-2 is a dual JFET amplifier that features low input
bias current, input voltage noise, input current noise, and rail-
to-rail output.
The combination of low noise and very low input bias currents
makes these amplifiers especially suitable for high impedance
sensor amplification. Unlike many competitive amplifiers, the
ADA4001-2 maintain their fast settling performance even with
substantial capacitive loads. Unlike many older JFET amplifiers,
the ADA4001-2 do not suffer from output phase reversal when
input voltages exceed the maximum common-mode voltage
range.

Fast slew rate and great stability with capacitive loads make the
ADA4001-2 a perfect fit for high performance filters. Low input
bias currents, low offset, and low noise result in a wide dynamic
range of photodiode amplifier circuits. Low noise and
distortion, high output current, Rail-to-Rail Output and
excellent speed make the ADA4001-2 a great choice for audio
frequency applications.
The ADA4001-2 is specified over the −40°C to +125°C
extended industrial temperature range.
The ADA4001-2 is available in 8-lead narrow SOIC, 8-lead.
