Description
AK8973S-L is a geomagnetism detection type electronic compass IC. It integrates magnetic sensors for detecting geomagnetism in the X-axis, Y-axis, and Z-axis, along with an arithmetic circuit for processing the signals from each sensor. This IC outputs four data in total as 8-bit digital values, including 3-axis magnetic sensor measured values and temperature sensor read value. By processing the magnetic sensor measured values with an external CPU, azimuth data can be obtained. It operates within the temperature range of -30°C to +85°C and requires an operating supply voltage of +2.5V to +3.6V. The compact 16-pin QFN package measures 4.0mm×4.0mm×0.7mm.
