GENERAL DESCRIPTION
The OP177 features the highest precision performance of any
op amp currently available. Offset voltage of the OP177 is only
10 V max at room temperature and 20 V max over the full
military temperature range of –55 C to +125 C. The ultralow

temperature.
The OP177’s open-loop gain of 12 V/ V is maintained over the
full 10 V output range. CMRR of 130 dB min, PSRR of
120 dB min, and maximum supply current of 2 mA are just a
few examples of the excellent performance of this operational
amplifier. The OP177’s combination of outstanding specifications
insure accurate performance in high closed-loop gain applications.

This low noise bipolar input op amp is also a cost effective
alternative to chopper-stabilized amplifiers. The OP177 provides
chopper-type performance without the usual problems of high
noise, low frequency chopper spikes, large physical size, limited
common-mode input voltage range, and bulky external storage
capacitors.
The OP177 is offered in both the –55 C to +125 C military,
and the –40 C to +85 C extended industrial temperature
ranges. This product is available in 8-pin ceramic and epoxy
DIPs, as well as the space saving 8-pin Small-Outline (SO) and
the Leadless Chip Carrier (LCC) packages.
