General Description
The output voltage of the MMA243F TMR angle sensor is proportional to the sine or cosine of the angle of a magnetic field applied parallel to the surface of the sensor, which can be provided by a small magnet positioned above the device. The MMA243F includes two Wheatstone bridges, which can be configured to output sine and cosine functions respectively. Each bridge includes four TMR sensor elements in a push-pull arrangement to produce a best-in-class peak-to-peak signal as large as 80% of the supply voltage, eliminating the need for...
