NJR releases the 0.05µV/°C max, Zero-Drift, Single Supply, Rail-to-Rail Output CMOS Operational Amplifier NJU7098AF1-C

2019-09-12 | Return

The NJU7098AF1-C is a low offset voltage and zero-drift operational amplifier. With an maximum input offset voltage of 15µV and offset drift of 0.05µV/°C, the NJU7098AF1-C is suitable for applications in which error sources cannot be tolerated. The NJU7098AF1-C operate from 3V to 10V with single supply. Rail-to-rail output swing , input common mode voltage within negative rail and 30mA high output current capability provided by the NJU7098AF1-C make low-side sensing or precision output buffer easy. The almost zero DC offset and offset drift are supported with a power supply rejection ratio and common mode rejection ratio at 130dB. Futuremore, typical open-loop voltage gain is 140dB. The NJU7098AF1-C includes a shutdown mode. Under logic control, the amplifiers can be switched from normal operation to shutdown current that is 15µA max and the output placed in a high- impedance state.
