PRELIMINARY INFORMATION
HALL-EFFECT,
(subject to change without notice) DIRECTION-DETECTION SENSOR ICS
September 6, 2000
The A3421xKA and A3422xKA Hall-effect, direction-detection sensor ICs are a new generation of special-function devices that
E1
E2 are capable of sensing the direction of rotation of a ring magnet. These transducers provide separate digital outputs that provide information on
X magnet rotation speed, direction, and magnet pole count. These devices eliminate the major manufacturing hurdles encountered in fine-pitch direction-detection applications, namely maintaining accurate mechani-
