The GSDM110 is a three-axis magnetometer that provides excellent temperature stability and high resolution. Based on Hall-effect technology, the device has a full-scale of ±48Gauss. Packaged in a 1.6×1.6×0.81 mm ball grid array (BGA), this device has an outstanding operating temperature range of -40°C to +85°C. The self-test function with internal magnetic source allows users to check the functioning of the sensor. The on-board non-volatile memory is able to store calibration data on-chip. The device may be configured to generate interrupt signals by the inertial DARY events and the timing of interrupt generators is programmable by end users on the fly. With on-bard temperature sensor, the device allows temperature to be read out via I2C/SPI protocol in a digital format. GSDM110 incorporates magnetic sensors for detecting terrestrial magnetism in the X-axis, Y-axis, and Z-axis, a sensor driving circuit, signal amplifier chain, and an arithmetic circuit for processing the signal from each sensor.
