MultiDimension MMA253F
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, eliminating the need for amplification in many applications.| Part No. | MMA253F |

GENERAL DESCRIPTION
The dual-axis output voltages of Additionally, the unique TMR Wheatstone bridge technology accurately compensates the output against changes in ambient temperature. This sensor is assembled in a compact LGA8 package of 3.0 mm 3.0 mm 0.9 mm. Operation A small magnet, placed above the MMA253F, can be used to provide a magnetic field in any desired orientation parallel to the plane of the MMA253F package. The magnetic field is detected by TMR sensors in the MMA253F that are composed of two magnetic layers. One layer of the...
