MXGM23X21G3-2a3xi2s0digital compass IC
The MXG2321 is a high sensitivity digital compass IC for measuring terrestrial magnetism in the X-axis,
Y-axis, and Z-axis. It combines magnetic sensors for detecting terrestrial magnetism, a sensor driving
circuit, low noise amplifier, high resolution ADC for each channel and control circuit for low power
computation. The MXG232x 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. With small footprint and low power consumption, the MXG2321 is
suitable for mobile phones and mobile GPS systems.
