The OP-177 features the highest precision performance of any op amp currently available. Offset voltage of the OP-177 is only 10µV typical, 25µV MAX over room temp. The ultra-low VOS of the OP-177 combines with its exceptional offset voltage drift (TCVOS) of 0.1µV/°C typical, 0.3µV/°C MAX, to eliminate the need for external VOS adjustment and increases system accuracy over temperature.
The OP-177's open-loop gain of 12V/µV typical is maintained over the full ±10V output range. CMRR of 130dB MIN, PSRR of 115dB MIN, and maximum supply current of 2mA are just a few examples of the excellent performance of this operational amplifier. The OP-177's combination of outstanding specifications insures 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 OP-177 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 OP-177 is offered at -40°C to +85°C extended industrial temperature ranges. This product is available in 8-pin epoxy DIP's, as well as the space saving 8-pin Small Outline (SO).
