A1183 Unipolar Hall-Effect Switch

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 produced at the output of the Hall sensor. This makes it difficult to process the signal and maintain an accurate, r.

Features

/ BENEFITS ♦ Chopper Stabilization s Extremely low switch-point drift s Low stress sensitivity ♦ One-time external programmability s Operate Point ♦ On-chip Protection s Supply transient protection s Robust ESD/EMC protection s Reverse-battery protection ♦ On-board Voltage Regulator s 3.8 V to 24 V operation Order by complete part number (i.e. A1182LUA). 1 The “LH” PPD is based on a 0.062" thick FR4, single-sided board using 2 oz. copper, with a 0.55 mm2 area of copper attached to the ground lead.
