The OP177GSZ is an Ultra Precision Operational Amplifier features 25µV offset voltage at room temperature. The ultralow VOS combines with its exceptional offset voltage drift (TCVOS) of 0.3µV/°C maximum to eliminate the need for external VOS adjustment and increases system accuracy over temperature. The OP177 open-loop gain of 12V/µV is maintained over the full ±10V output range. CMRR of 130dB minimum, PSRR of 120dB minimum and maximum supply current of 2mA are just a few examples of the excellent performance of this operational amplifier. The combination of outstanding specifications 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 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.
