Download 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 the rotating magnetic field in the sensor plane, generating two sinusoidal output signals reflecting the angle θ between the sensor and the direction of the magnetic field. The function of the two outputs corresponding to the rotating field is Sin(2θ) and Cos(2θ).

Features

• 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
• Allows large working spacing
• High sensitivity
• Excellent precision even with weak operation magnetic field
• Negligible hysteresis effect
• Minimal output offset level
