Overview
The AD22151YRZ-RL, produced by Analog Devices Inc., is a linear magnetic field transducer. This sensor outputs a voltage that is proportional to the magnetic field applied perpendicularly to the package top surface. It combines integrated bulk Hall cell technology and instrumentation circuitry to minimize temperature-related drifts associated with silicon Hall cell characteristics. The AD22151 is designed for single 5 V supply operation and achieves low drift offset and gain over a wide temperature range of –40°C to +150°C.
