CHOPPER-STABILIZED, PRECISION HALL-EFFECT SWITCH
The A3240-- Hall-effect switch is an extremely temperature-stable and stress-resistant sensor 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.
The device includes on a single silicon chip a
voltage regulator, Hall-
voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, and a short-circuit protected open-collector output to sink up to 25 mA.
