OP177GS

Product Summary

The OP177GS is an Ultra precision Operational Amplifier. The OP177GS features one of the highest precision performance of any op amp currently available. Offset voltage of the OP177GS is only 25 μV maximum at room temperature. The ultralow VOS of the OP177GS combines with its exceptional offset voltage drift (TCVOS) of 0.1 μV/°C maximum to eliminate the need for external VOS adjustment and increases system accuracy over temperature. The OP177GS 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 OP177GS ensures 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 OP177GS 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 OP177GS is offered in the -40°C to +85°C ;-40°C to +85°C extended industrial temperature ranges.
