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.

3150 PROGRAMMABLE, CHOPPERSTABILIZED, HALL-EFFECT SWITCH The A3150JLT and A3150JUA programmable switches provide tooth/valley recognition in large gear-tooth sensing applications.
Each sensor consists of a single element, chopper-stabilized Hall-effect IC that can be programmed to the desired magnetic switch point, optimizing sensor airgap and timing accuracy performance after final packaging.
The small package can be easily assembled and used in conjunction with a wide variety of gear/target s
