Data Sheet 27650.1 3421 AND 3422 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 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- LOGIC T VCC is a C 1 2 3 4 5 SUPPLY DIRECTION GROUND E1 OUTPUT SPEED 1xKA PRODUxKA; Dwg.
