Allegro MicroSystems APS12202 and APS12212 Precision Hall-Effect Latches are extremely temperature-stable and stress-resistant sensor ICs that are ideal for extended temperature range operations (up to 150°C). The dynamic offset cancellation in these latches allows for enhanced high-temperature performance. This reduces the residual offset voltage normally caused by device package overmolding, temperature dependencies, and thermal stress. The APS12202 and APS12212 hall-effect latches are identical except for their magnetic switch points. These latches are equipped with a voltage regulator, a Hall voltage generator, a small-signal amplifier, chopper stabilization, and a Schmitt trigger on a single chip.
