GENERAL DESCRIPTION
MA7902, 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.
