Omnipolar TMR Datasheet LGA8L LF53464-08TMR
Omnipolar Magnetic Sensor Description
The LF53464-08TMR angle sensor features a dual-axis, orthogonal
push-pull Wheatstone bridge architecture. Each bridge integrates
four high-sensitivity TMR (Tunnel Magnetoresistor) elements,
delivering output voltage of up to 65% of the supply voltage. This
strong signal output minimizes the need for external amplification
or additional processing circuitry. The sensor also adjusts for
ambient temperature variation.
When a magnet is positioned above the sensor to create a
magnetic field parallel to the chip surface, the chip’s dual-axis
output produces voltage signals in a sine/cosine relationship
proportional to the angle of the magnetic field.
The LF53464-08TMR is offered in a compact LGA8L package,
measuring 3 mm × 3 mm × 0.75 mm. Features & Benefits Additional Information ■ Tunneling Magnetoresistance
