OP07CPZ vs OP177GPZ vs OP07CP Comparison

The OP07CPZ 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.

The OP177GPZ is an Ultra-precision Operational Amplifier features one of the highest precision performances of any operational amplifier currently available. Offset voltage of this is only 25µV maximum at room temperature. It 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. It 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.

These devices offer low offset and long-term stability by means of a low-noise, chopper less, bipolar-input-transistor amplifier circuit. For most applications, external components are not required for offset nulling and frequency compensation. The true differential input, with a wide input-voltage range and outstanding common-mode rejection, provides maximum flexibility and performance in high-noise environments and in non-inverting applications. Low bias currents and extremely high input impedances are maintained over the entire temperature range. The OP07 is unsurpassed for low-noise, high-accuracy amplification of very-low-level signals.
