Measure angles with precision magnetic sensors which compensate for thermal drift

To deliver high performance in demanding temperatures and environments these magnetic angle sensors measure from 0 to 360° with an X and Y axis sensing direction, and adjust for variation in the ambient temperature.

Output voltage can be up to 65% of the supply voltage, and the LF53464 angle sensor features a dual-axis, orthogonal push-pull Wheatstone bridge architecture, in which each bridge integrates four high-sensitivity TMR elements. The strong signal output reduces the need for external amplification or for an additional circuit to handle processing.

When a magnet is positioned above the sensor to create a magnetic field parallel to the chip surface, the dual-axis output produces voltage signals in a sine/cosine relationship which is proportional to the angle of the magnetic field.

Offering differential output, the LF53464 saves space with a compact LGA8L package which measures 3mm x 3mm x 0.75mm.

By maintaining an angular error of less than 0.8° over a magnetic field of 200 to 800 Gauss, the LF53466 enables exceptional accuracy and thermal stability. Offering two bridges in a compact TSSOP8 package, the LF53466 features three-phase alignment with UVW output channels which match the phases of standard AC or brushless motor winding.
