... For the A1120, a south pole of sufficient strength turns the output on. Removal of the magnetic field turns the output off. The A1125 is complementary to the A1120 in that, for the A1125, a south pole turns the output off, and removal of the magnetic field turns the output on. 3-pin SIP (suffix UA) Two package styles provide a magnetically optimized package for most applications ...

... A of figure 1). When the OP magnetic field is reduced below the release point, B output goes high (turns off). The output of the A1125 devices switches high (turns off) when a magnetic field perpendicular to the Hall element exceeds the operate point threshold, B panel B of figure 1). When the magnetic field is reduced below the release point the device output goes low (turns on) ...

... A1120 and Chopper Stabilized Precision Hall Effect Switches A1125 Chopper Stabilization Technique When using Hall effect technology, a limiting factor for switchpoint accuracy is the small signal voltage developed across the Hall element. This voltage is disproportionally small relative to the offset that can be produced at the output of the Hall ele- ment ...
