low offset voltage and drift. Laser-trimmed offset,
drift and input bias current virtually eliminate the need
for costly external trimming. The high performance
and low cost make them ideally suited to a wide range
of precision instrumentation.

an effective alternative to chopper-stabilized amplifi-
ers. The low noise of the OPA177 maintains accuracy.

DISCHARGE SENSITIVITY
Any integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. ESD can cause damage ranging
from subtle performance degradation to complete device
failure. Precision integrated circuits may be more suscep-
tible to damage because very small parametric changes
could cause the device not to meet published specifications.
Burr-Brown’s standard ESD test method consists of five
1000V positive and negative discharges (100pF in series
with 1.5kΩ) applied to each pin.
Failure to observe proper handling procedures could result
in small changes to the OPA177’s input bias current.
