    SS1101

    General Description

    The SS1101 is a unipolar Hall-effect sensor IC fabricated from CMOS technology. The device integrates a voltage regulator, Hall sensor with dynamic offset cancellation system, small signal amplifier, Schmitt trigger and an open-drain output driver. With suitable output pull up, they can be used with bipolar or CMOS logic circuits.
