MXM1120SO digital Hall sensor IC

The MXM1120SO is a multi-function Hall-effect sensor designed with mixed signal CMOS technology. The device integrates Hall elements, dynamic offset cancellation system, a programmable gain amplifier, low power ADC and arithmetic logic in a single chip. Bop, Brp, operation magnetic polarity and operation period are programmable by I2C interface. Off the-shelf software is available to transform magnetic field strength into the angle between the magnet and the device with robust algorithm.
