GENERAL DESCRIPTION OP177GPZ

The OP177GPZ OP177 features one of the highest precision performance of

any operational amplifier currently available. Offset voltage of the

OP177 is only 25 μV maximum at room temperature. The ultralow

VOS of the OP177 combines with the exceptional offset voltage

drift (TCVOS) of 0.3 μV/°C maximum to eliminate the need for

external VOS adjustment and increases system accuracy over

temperature.

The OP177 open-loop gain of 12 V/μV is maintained over the full

±10 V output range. CMRR of 130 dB minimum, PSRR of 120 dB

minimum, and maximum supply current of 2 mA are just a few

examples of the excellent performance of this operational amplifier.

The combination of outstanding specifications of the OP177

ensures accurate performance in high closed-loop gain

applications.
