A1301

The A1301 and A1302 are continuous-time, ratiometric, linear Hall-effect sensors.  They are optimized to accurately 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.

The Hall-effect integrated circuit included in each device includes 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 minimizes many of the  problems normally associated with low voltage level analog signals.
