Omnipolar TMR Datasheet TSSOP8 LF53466-08TMR
Omnipolar Magnetic Sensor Description
The LF53466TMR angle sensor features a dual-axis, orthogonal
push-pull Wheatstone bridge architecture. Each bridge incorporates
four high-sensitivity TMR (Tunnel Magnetoresistor) elements,
providing excellent performance even in demanding temperatures
and environments.
When a magnet is positioned above the chip to create a magnetic
field parallel to its surface, the chip’s dual-axis output produces
voltage signals with a sine/cosine relationship proportional to the
angle of the magnetic field.
The LF53466TMR delivers exceptional accuracy, maintaining an
angular error of less than 0.8 degrees when operating within a
magnetic field range of 200 to 800 Gauss. The LF53466-08TMR
is offered in a compact TSSOP8 package. Features & Benefits Additional Information ■ Tunneling Magnetoresistance
