OP07CDE4 vs OP07CDR vs OP07DRZ Comparison

General Purpose Amplifier 1 Circuit 8-SOIC

These devices offer low offset and long-term stability by means of a low-noise, chopperless, 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 noninverting applications. Low bias currents and extremely high input impedances are maintained over the entire temperature range.

The OP07DRZ is a Maximum Offset Voltage Operational Amplifier that integrates low power (1.1mA typical), low input bias current (±1nA maximum) and high CMRR/PSRR (130dB). It provides higher accuracy than industry-standard OP07-type amplifiers due to iPolar™ process, which supports enhanced performance in a smaller footprint. These performance enhancements include wider output swing, lower power and higher CMRR (common-mode rejection ratio) and PSRR (power supply rejection ratio). The OP07D maintains stability of offsets and gain virtually regardless of variations in time or temperature. Excellent linearity and gain accuracy can be maintained at high closed-loop gains. This is ideal to use in medical and industrial instrumentation, RTDs, strain bridges and shunt current measurements as well as precision filters.
