A3150 - PROGRAMMABLE/ CHOPPERSTABILIZED/ HALL-EFFECT SWITCH

Chopper-Stabilized Technique.

These devices use a proprietary dynamic offset cancellation technique, with an internal high-frequency clock to reduce the residual offset voltage of the Hall element that is normally caused by device overmolding, temperature dependencies, and thermal stress.
