Asahi Kasei Microdevices AK8973
AK8973 is a geomagnetism detection type electronic compass IC. The small package of AK8973 integrates magnetic sensors for detecting geomagnetism in the X-axis, Y-axis, and Z-axis, and arithmetic circuit for processing the signal from each sensor. By processing the magnetic sensor measured values with an external CPU, azimuth data can be obtained.- Min Voltage : 2.5V
- Max Voltage : 3.6V
- Max Operating Temp : 85°C
- Min Operating Temp : -30°C
