MMLP57F TMR Linear Sensor General Description The MMLP57F linear sensor utilizes a unique push-pull Wheatstone bridge composed of four unshielded TMR sensor elements. The unique bridge design provides a high sensitivity differential output that is linearly proportional to a magnetic field applied parallel to the surface of the sensor package, and it provides superior temperature compensation of the output. The MMLP57F is available in a 6 mm × 5 mm × 1.7 mm SOP8 package.

At low fields the MMLP57F response is highly linear, and it is not harmed when the sensor is driven into saturation.
