Allegro MicroSystems A1321/A1322/A1323 Ratiometric Linear Hall Effect Sensor Datasheet

The A132X family of linear Hall-effect sensors are optimized, sensitive, and temperature-stable. These ratiometric Hall-effect sensors provide a voltage output that is proportional to the applied magnetic field. The A132X family has a quiescent output voltage that is 50% of the supply voltage and output sensitivity options of 2.5mV/G, 3.125mV/G, and 5mV/G. The features of this family of devices are ideal for use in the harsh environments found in automotive and industrial linear and rotary position sensing systems. Each device has a BiCMOS technology.
