They are optimized to accurately provide Ratiometric rail-to-rail output a voltage output that is proportional to an applied magnetic 4.5 to 6.0 V operation field. These devices have a quiescent output voltage that is Solid-state reliability 50% of the supply voltage. Two output sensitivity options Factory-programmed at end-of-line for optimum are provided: 2.5 mV/G typical for the A1301, and 1.3 mV/G performance typical for the A1302. Robust ESD performance 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 Packages: and offset trim adjustments made at end-of-line during the 3-Pin SOT23W (suffix LH) 3-Pin SIP (suffix UA) 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 40C to 125C. 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, T) with Not to scale 100% matte tin plated leadframes.
