A1301/2 Ratiometric Linear Hall Effect Sensors, Allegro Microsystems
●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.
●Low-noise output
●Fast power-on time
●Ratiometric rail-to-rail output
●4.5 V to 6.0 V operation
●Solid-state reliability
