100% (3) Sens(25.C) Ratiometric. The A1301 and A1302 feature a ratiometric output. This means that the quiescent voltage output, VOUTQ, and the magnetic sensitivity, Sens, are proportional to the supply voltage, VCC. The ratiometric change (%) in the quiescent voltage output is defined as: VOUTQ(VCC) VOUTQ(5V).VOUTQ(.V) = . 100% (4) 5V VCC and the ratiometric change (%) in sensitivity is defined as: Sens(VCC) Sens(5V) .Sens(.V) = . 100% (5) VCC 5V Linearity and Symmetry.

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 Packages: 3 pin SOT23W (suffix LH), and 3 pin SIP (suffix UA) Not to scale Description 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 ou
