A1301 and A1302 Continuous-Time Ratiometric Linear Hall Effect Sensor ICs Low-noise output Fast power-on time Ratiometric rail-to-rail output to V operation Solid-state reliability Factory-programmed at end-of-line for optimum performance Robust ESD performance Packages 3 pin SOT23W suffix LH , and 3 pin SIP suffix UA Not to scale 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 mV/G typical for the A1301, and 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 Class A 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 to 125°C. Two device package types are available LH, a 3-pin SOT23W type for surface mount, and UA, a 3-pin ultramini SIP for through-hole mount. They are lead Pb free suffix, with 100% matte tin plated leadframes.
