ADA4523-1 Datasheet Zero Drift Op Amp

Manufacturer: Analog Devices

Overview: Data Sheet 36 V, Low Noise, Zero Drift Op Amp ADA4523-1.

General Description

The ADA4523-1 is a high voltage, low noise, zero drift op amp that offers precision dc performance over a wide supply range of 4.5 V to 36 V.

Offset voltage and 1/f noise are suppressed, allowing this op amp to achieve a maximum offset voltage of ±4 µV and a 0.1 Hz to 10 Hz input noise voltage of 88 nV 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.
