GENERAL DESCRIPTION
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 -40C to 150C with supplies up to +20 Vdc. The sensor is designed to remain functional during voltage transients up to +27V.
FEATURES
Speed and direction from 0Hz to 2500Hz
Air gap diagnostics
2-wire current-loop operation
Wide Operating Temperature Range
Functional during temperature excursions to 190C
Reverse Supply Protected (-30V)
APPLICATIONS
Automotive
Wheel speed and direction sensing
