3.8 × 4.9 × 1.75 mm3 8-pin SO8 package and 2.0 × 2.0 × 0.75 mm3 DFN package
180° absolute angle detection
14 bit resolution
1000 Hz output data rate


iSentek IST8210 is a magnetic angle sensor with dimensions of 3.8 × 4.9 × 1.75 mm3 in 8-pin SO8-packaging and 2.0 × 2.0 × 0.75 mm3 in DFN-packaging. The sensor comprises two independent full Wheatstone bridges based on anisotropic magnetoresistance (AMR) effect.
The sensor detects the direction of rotating magnetic field in the sensor plane, generating two sinusoidal output signals reflecting the angle θ between the sensor and direction of magnetic field. The function of the two outputs corresponding to the rotating field is Sin(2θ) and Cos(2θ).


Non-contact and wear-free angle measurement
Insensitive to dust, water, oil, or other contaminations
Excellent robustness against shocks and vibrations
Constant sensitivity at very high operation field
Allowing large working spacing
High sensitivity
Excellent precision even with weak operation magnetic field
Negligible hysteresis effect
Minimal output offset level
