the sc4616 family of programmable linear hall effect sensor ics is designed specifically for angular position, and ac/dc current measurement etc. the accuracy of these devices is enhanced via programmability on the output pin for end-of-line optimization without the added complexity and cost of a fully programmable device.

these ratiometric hall effect devices provide a voltage output that is proportional to the applied magnetic field. both the quiescent voltage output and magnetic sensitivity are user adjustable. the quiescent voltage output can be set to 2.5v or 0.5v, and the sensitivity adjusted between 3 mv/gs and 16 mv/gs. programming selections also exist for output polarity and temperature compensation.

each bi-cmos monolithic circuit integrates a hall element, temperature-compensating circuitry to reduce the intrinsic sensitivity drift of the hall element, a small-signal high-gain amplifier, a low-impedance output stage, a proprietary dynamic offset cancellation technique and trimming unit.
