Description
The AMR132x is an omnipolar magnetic switch integrated with anisotropic magnetoresistance (AMR) magnetic sensor and CMOS circuitry, which is able to detect the change of magnetic field and output high and low voltage signals for high accuracy position detection. The AMR132x series switch can detect magnetic fields from all directions in the plane, enabling 360° sensing. It provides 100 Hz sampling frequency, 1 μA power consumption, and a wide range of operating voltages from 1.8 V to 5.5 V. It has excellent thermal stability and immunity to stray field interference. The AMR132x available in the compact SOT23-3 package. Features and Benefits
