3-axis digital compass IC
MXG2320
The MXG3300 is a high-sensitivity digital compass IC with ultra-small package for measuring terrestrial
magnetism in the X-axis, Y-axis, and Z-axis. It combines magnetic sensors for detecting terrestrial
magnetism, sensor driving circuit, low noise amplifier, high resolution ADC for each channel, embedded
FIFO and control circuit for low power computation.
The MXG3300 supports for low power mode in addition to normal mode to extend battery life. The built-in
temperature sensor can compensate for offset drift caused by non-linear ADC characteristics for each
temperature. The embedded FIFO dramatically reduces access count from the host to the sensor
enabling lower power consumption and lower load to the host. Maximum 200Hz output data rate will
make more prompt response for pseudo fusion-sensor functions. With small footprint and low power
consumption, the MXG2320 is suitable for mobile phones and mobile GPS systems.
