A1302

• Low-noise output
• Fast power-on time
• Ratiometric rail-to-rail output
• 4.5 to 6.0 V operation
• Solid-state reliability
• Factory-programmed at end-of-line for optimum performance
• Robust ESD performance

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 of A1301 and A1302 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 of A1301 and A1302 on a single chip minimizes many of the problems normally associated with low voltage level analog signals.
