TMR3005 angle sensor adopts two orthogonal

push-pull Wheatstone bridge design, and each

bridge contains four high-sensitivity TMR sensing

elements to produce a best-in-class peak-to-peak

output signal as large as 65 of the supply voltage,

thereby eliminating many external signal amplifying

and processing circuit needed in the applications.

The voltage signal output by the two axes of the chip

has a sine and cosine relationship with the angle of

the magnetic field, when a magnet is placed above

the TMR3005 chip to provide an operating magnetic

field parallel to the surface of the chip in general

angle sensor application. Additionally, the TMR full

bridge technology accurately compensates the

output against changes in ambient temperature.

This high performance TMR3005 angle sensor

is available in packaging form factors of compact

LGA8L (3 mm × 3 mm × 0.75 mm).
