Description
The A3241 and A3242 integrated circuits are unipolar Halleffect switches with digital outputs. These devices are suited for operation over extended temperature ranges, up to +150°C. Superior high-temperature performance is made possible through an Allegro® dynamic offset cancellation, which reduces the residual offset voltage normally caused by device overmolding, temperature excursions, and thermal stress.
The A3241 and A3242 Hall-effect switches include the following on a single silicon chip: voltage regulator, Hallvoltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, and a short circuit...
