IST8210 DATASHEET

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).

Features

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
