Ultraprecision Operational Amplifier
The OP177 features one of the highest precision performance of any op amp currently available. Offset voltage of the OP177 is only 25uV maximum at room temperature. The ultralow Vos of the OP177 combines with its exceptional offset voltage drift (TCVos) of 0.1uV/°C maximum to eliminate the need for external Voa adjustment and increases system accuracy over temperature. The OP177 open-loop gain of 12V/uV 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 of the OP177 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.
