Overview
The OP213ESZ-REEL7 is a low noise, low drift single-supply operational amplifier produced by Analog Devices Inc. This component is part of the OPx13 family, which is designed for systems that require high precision and low noise, particularly in applications where internal calibration is used to correct for offset and gain but not for temperature drifts and noise. The OP213 is optimized for these parameters, making it suitable for a variety of precision analog applications.
