GENERAL DESCRIPTION

MA7908, a linear Hall-effect sensor, is composed of hall sensor, linear amplifier and

output stage. 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 voltage is set by the supply voltage and varies in

proportion to the strength of the magnetic field. Typical operation current is 3.3 mA and

operating voltage range is 2.8 volts to 5.5 volts.

The package style available provides magnetically optimized solutions for most

applications.
