GENERAL DESCRIPTION

The MA7952 is a dual outputs linear Hall-effect sensor suited to detect the speed and

the position of ferromagnetic or the permanent magnet structures. The linear Hall sensor

have an operating Temperature range of -40°C to +125°C, appropriate for commercial,

consumer, and industrial environments.

The high sensitivity of Hall-effect sensor accurately tracks extremely small changes in

magnetic flux density. The linear output voltages are set by the supply voltage and vary in

proportion to the strength of the magnetic field. Typical operation current is 13 mA and

operating voltage range is 2.8 volts to 5.5 volts.

The package style available provides magnetically optimized solutions for most

applications.
