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.
Key Feature
 Magnetometer device for magnets on external devices
