A3423 Dual Channel Hall Effect Direction Detection Sensor IC

The A3423 is a dual-channel Hall-effect sensor IC ideal for use in speed and direction sensing applications incorporating encoder ring-magnet targets. The A3423 provides various output signals that indicate speed and direction of target rotation. The Hall elements are both photolithographically aligned to better than 1 ?m. Maintaining accurate displacement between the two active Hall elements eliminates the major manufacturing hurdle encountered in fine-pitch detection applications. The sensor ICs are highly sensitive, temperature-stable magnetic sensor ICs ideal for use in harsh automotive and industrial environments
