A1242 - Allegro MicroSystems

A1242 Two-Wire Chopper-Stabilized Hall Effect Latch

The A1242 Hall effect latch is a two-wire latch especially suited for operation over extended temperature ranges, from –40 to +150°C. Superior high-temperature performance is made possible through the Allegro dynamic offset cancellation technique, which reduces the residual offset voltage normally caused by device overmolding, temperature dependencies, and t.
