General Description

angle of a magnetic field applied parallel to the surface of the sensor, which can be provided by a

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 0.75% of the supply voltage. Additionally, the unique TMR Wheatstone bridge technology

accurately compensates the output against changes in ambient temperature. This sensor is

assembled in an ultra small SOP8 package

Operation

sensor output as a function of the angle of the applied magnetic field using a 6 mm diameter, 2.5

mm thick magnet and at 1 V supply.
