AD22157 Datasheet Wheel Speed Sensor

Manufacturer: Analog Devices

Overview: PRELIMINARY TECHNICAL DATA Wheel Speed Sensor For ABS Systems Preliminary Technical.

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.

Key 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).
