Electronic compass

The electronic compass is a high sensitivity digital magnetic sensor IC for measuring terrestrial magnetism in the X-axis, Y-axis, and Z-axis. It combines Hall element for measuring terrestrial magnetism, sensor driving circuit, low noise amplifier, high resolution ADC for each channels and control circuit for low power computation.

The MXG product family features low power mode for extending battery life and tiny size for small form factor. An embedded temperature sensor can compensate offset drift caused by non-linear ADC characteristics for wide temperature range. With low power consumption and small footprint and, the MXG product family is suitable for mobile phones, IoT devices and GPS systems.
