AD22157

The AD22157 is a mixed signal magnetic field transducer designed for applications where both speed sensing and direction sensing of a ferrous target wheel are required over a wide speed range.

The device operates from a 2-wire high compliance current loop and is suitable for continuous operation from -40°C to 150°C with supplies up to +20 Vdc. The sensor is designed to remain functional during voltage transients up to +27 V.
