iSentek IST8210S/D is an anisotropic magneto-resistance (AMR) digital magnetic angle sensor which detects the orientation of a magnetic field. It is an integrated chip with magnetic sensors and control ASIC with 14-bit ADC output. IST8210S/D’s two sinusoidal output signals (Sin(2θ) and Cos(2θ)) reflecting the angle θ between the sensor and direction of magnetic field are generated for the calculation of absolute angles within 180 degree. IST8210S/D operates in saturation region therefore has high tolerance to process and temperature variation of magnet and the alignment error of PCB mounting. Both end-of-shaft and side-shaft mounting configurations are supported. iSentek dynamic calibration algorithms are provided for the users to obtain an angle error of 0.25°.
