High accuracy 3 axis magnetic sensor QST QMC6308 featuring 16 bit ADC and temperature compensation technology
Product Overview
The QMC6308 is a three-axis magnetic sensor integrating magnetic sensors and signal conditioning ASIC onto a single silicon chip. Packaged in a wafer-level chip scale package (WLCSP), it is designed for applications such as e-compass, map rotation, gaming, and personal navigation in mobile and wearable devices. Leveraging advanced magneto-resistive technology and a custom-designed 16-bit ADC ASIC, it offers low noise, high accuracy, low power consumption, offset cancellation, and temperature compensation, enabling 1 to 2 compass heading accuracy. The device features an IC serial bus for easy interface and is available in a compact 0.8x0.8x0.5mm 4-pin WLCSP package.
