Analog Devices Inc. ADA4523-1 Zero Drift Op Amp

Analog Devices Inc. ADA4523-1 Zero Drift Op Amp features precision DC performance over a wide supply range of 4.5V to 36V. The ADA4523-1 achieves a maximum offset voltage of ±4µV and a 0.1Hz to 10Hz input noise voltage of 88nV p-p typical. The self-calibrating circuitry of the ADA4523-1 results in low offset voltage drift with temperature (0.01 µV/°C maximum) and zero drift over time. The ADA4523-1 also uses on-chip filtering to achieve high immunity to electromagnetic interference (EMI).
