‘Zero-drift’ op-amp works across 4.5 to 36V

ADA4523-1 is a precision ‘zero-drift’ op-amp from Analog Devices that works across 4.5V to 36V, drawing 6mA worst case.

The output is rail-to-rail, and the input includes the negative rail – working from 100mV below the negative rail to 1.5V below the positive rail.

Maximum offset voltage is ±4µV and, due to self-calibrating circuitry, this drifts at only 0.01µV/°C (max at 5V) – and ADI claims zero drift over time.
