General Description
The dual-axis output voltages of the MMA253F TMR angle sensor are proportional to the sine and 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 MMA253F 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 100% of the supply voltage,...
