... VCC A1220-DS, Rev. 11 A1220, A1221, A1222, and A1223 Description The A1220, A1221, A1222, and A1223 Hall-effect sensor ICs are extremely temperature-stable and stress-resistant devices especially suited for operation over extended temperature ranges to 150°C. Superior high-temperature performance is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device overmolding, temperature dependencies, and thermal stress ...

... A1220, A1221, Chopper Stabilized Precision Hall Effect Latches A1222, and A1223 Operation The output of these devices switches low (turns on) when a mag- netic field perpendicular to the Hall element exceeds the operate point threshold, B (see panel A of figure 1). After turn-on, the OP output voltage is V ...

... A1220, A1221, Chopper Stabilized Precision Hall Effect Latches A1222, and A1223 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 ...
