A1181 switch equivalent, unipolar hall-effect switch.
/ BENEFITS
* Chopper Stabilization s Extremely low switch-point drift s Low stress sensitivity
* One-time external programmability s Operate Point
* On-chip P.
This device uses a patented high frequency chopper-stabilization technique on Allegro's new DABIC5 BiCMOS wafer fabrica.
Chopper-Stabilization Technique. A limiting factor for switch point accuracy when using Hall effect technology is the small signal voltage developed across the Hall plate. This voltage is proportionally small relative to the offset that can be produc.
