QST QMC6309

The QMC6309 is a three-axis magnetic sensor, which integrates magnetic sensors and signal condition ASIC into one silicon chip. This wafer level chip scale package (WLCSP) is targeted for applications such as e-compass, map rotation, gaming and personal navigation in mobile and wearable devices. The QMC6309 is based on state-of-the-art, high resolution, magneto-resistive technology. Along with the custom-designed 16-bit ADC ASIC, it offers the advantages of low noise, high accuracy, low power consumption, offset cancellation and temperature compensations. QMC6309 enables 1° to 2° compass heading accuracy. The I²C serial bus allows for easy interface.
