OP177FSZ vs OP177FSZ-REEL vs OP07CSZ Comparison

The OP177FSZ is a high precision Operational Amplifier 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. Offset voltage of the OP177 is only 25µV maximum at room temperature. The ultralow VOS of the OP177 combines with the 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 of the OP177 ensures accurate performance in high closed-loop gain applications.

The OP07CSZ is an Ultralow Offset Voltage Operational Amplifier features low input bias current and high open-loop gain. It has very low input offset voltage that is obtained by trimming at the wafer stage. These low offset voltages generally eliminate any need for external nulling. The low offset and high open-loop gain make the OP07 particularly useful for high gain instrumentation applications. The wide input voltage range of ±13V minimum combined with a high CMRR and high input impedance provide high accuracy in the non-inverting circuit configuration. Excellent linearity and gain accuracy can be maintained even at high closed-loop gains. Stability of offsets and gain with time or variations in temperature is excellent. The accuracy and stability of the OP07, even at high gain, combined with the freedom from external nulling have made it an industry standard for instrumentation applications.
