Description

The TMR308x series high-precision magnetic angle sensor adopts two orthogonal push-pull Wheatstone bridge design, and each bridge contains four high-sensitivity TMR sensing elements. Such design effectively compensates thermal drift ensuring high performance in harsh conditions.

The voltage signals generated by the two sensor axes exhibit a sinusoidal relationship with the angle of the magnetic field in general angle sensor applications, when a magnet is positioned above the TMR308x sensor to provide a magnetic field parallel to sensor surface.

The TMR308x achieves low angle error under 0.8 degree for applied magnetic field between 200 Gs and 800 Gs. The TMR308x series are available in SOP8 with P/N TMR308xP and TSSOP8 with P/N TMR308xTP.
