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.
