OHHALLSENSOR MMLP57F Tmr linear sensor Datasheet

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.

Transfer Curve
The following figure shows the response of the MMLP57F to an applied magnetic field in the range of
±30 Oe (left) and ±200 Oe (right) when the MMLP57F is biased at 1 V. At low fields the MMLP57F
response is highly linear, and it is not harmed when the sensor is driven into saturation.
