The Allegro Microsystems A1301 and A1302 are continuous-time, ratiometric, linear Hall-effect sensor ICs. They provide a voltage output that is proportional to an applied magnetic field. These devices have a quiescent output voltage that is 50% of the supply voltage. Two output sensitivity options are provided: 2.5 mV/g typical for the A1301, and 1.3 mV/g typical for the A1302.
Each IC has a Hall sensing element, a linear amplifier, and a CMOS Class A output structure. Integrating the Hall sensing element and the amplifier on a single chip minimises the issue often associated with low voltage level analogue signals.
They are ideal for use in position sensing systems, for both linear target motion and rotational target motion.
