DESCRIPTION
The OPA177 precision bipolar op amp feature very
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.
The low quiescent current of the OPA177 dramati-
cally reduce warm-up drift and errors due to thermo-

electric effects in input interconnections. It provides
an effective alternative to chopper-stabilized amplifi-
ers. The low noise of the OPA177 maintains accuracy.
OPA177 performance gradeouts are available. Pack-
aging options include 8-pin plastic DIP
and SO-8 surface-mount packages.

NOTES: (1) Long-Term Input Offset Voltage Stability refers to the averaged trend line of VOS vs time over extended periods after the first 30 days of operation. Excluding
the initial hour of operation, changes in VOS during the first 30 operating days are typically less than 2µV. (2) Sample tested. (3) Guaranteed by design. (4) Guaranteed
by CMRR test condition. (5) To insure high open-loop gain throughout the ±10V output range, AOL is tested at –10V VO 0V, 0V VO +10V, and –10V VO +10V.
(6) Guaranteed by end-point limits.
