3150 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. This technique produces devices that have an extremely stable quiescen.
