The OP113FSZ is a dual low-noise, low-drift precision amplifier manufactured by Analog Devices. It is a single-supply (SGL-Supply) part that can be operated up to +18 V, and down to a single +5 V supply, thanks to its power rails and modern input stages. It features a wide gain range of 1.0 to 100 V/V and a low noise level of 5.5 nV/vHz at 10 kHz. The part also offers low 1/f, low power, and fast settling time for more accurate sensor readings and operation on single-supply systems. The OP113FSZ is an optimized circuit that can help reduce high-noise levels in industrial, medical, test and measurement, and automotive measurements.
