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 sensor ICs. 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 circuit, a linear amplifier, and a CMOS ClassA

output structure. Integrating the Hall circuit and the amplifier

on a single chip minimizes many of the problems normally

associated with low voltage level analog signals.

High precision in output levels is obtained by internal gain

and offset trim adjustments made at end-of-line during the

manufacturing process.

These features make the A1301 and A1302 ideal for use in

position sensing systems, for both linear target motion and

rotational target motion. They are well-suited for industrial

applications over extended temperature ranges, from –40°C

to 125°C.
