DESCRIPTION
The OPA671 is a FET-input monolithic operational
amplifier featuring wide bandwidth and fast settling
time. Fabricated using Burr-Brown’s
mentary bipolar process, it provides an excellent combination of high speed, accuracy, and high output
current.
The OPA671 is versatile, operating from ±4.5V to
±18V power supplies. It can deliver ±10V signals into
a 200Ω load at slew rates of 100V/µs. OPA671’s
input provides input bias current thousands of times
lower than bipolar-input wideband op amps.
The OPA671 is internally compensated to be unity-gain
stable, allowing use in the widest range of applications.
The OPA671 is available in an 8-pin plastic DIP, rated
for the industrial temperature range.

An integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet published
specifications.
