GENERAL DESCRIPTION
The
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
accuracy in medical instruments, electronic measurement, and
automated test equipment. Unlike many competitive amplifiers,
the
substantial capacitive loads. Unlike many older JFET amplifiers,
the
when input voltages exceed the maximum common-mode
voltage range.
