The A1321/A1322/A1323 is a linear Hall-effect sensor from Allegro MicroSystems with a ratiometric rail-to-rail output proportional to the applied magnetic field. It is ideal for use in harsh environments in automotive and industrial linear and rotary position sensing systems.
The A1321/A1322/A1323 family consists of ratiometric linear Hall-effect sensors optimized for high-temperature operation. These devices provide a voltage output proportional to the applied magnetic field and are available in 3-pin single in-line (UA) and 3-pin surface mount (LH) packages. The family features a quiescent output voltage of 50% of the supply voltage and offers sensitivity options of 2.5mV/G, 3.125mV/G, and 5mV/G.
