General Description
The MMLH45F linear sensor utilizes a unique push-pull Wheatstone bridge composed of four
unshielded TMR sensor elements. This 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,
in addition to providing superior temperature compensation of the output. The MMLH45F is
available in a 6 mm  5 mm  1.7 mm SOP8 package.

Transfer Curve
The following figures show the response of the MMLH45F to an applied magnetic field in the
range of ±15 Oe (left) and ±200 Oe (right) when the MMLH45F is biased at 1 V. At low fields the
MMLH45F response is highly linear, and it is not harmed when driven into saturation.
