The CYD8526 is a dual-channel Hall-effect sensor IC ideal for use in speed and direction sensing applications incorporating encode ring-magnet targets. The Hall elements are both photo lithographically aligned to better than 1um. Maintaining accurate displacement between the two active Hall elements eliminates the major manufacturing hurdle encountered in fine-pitch detection applications. The CYD8526 is a sensitive, temperature-stable magnetic device suitable for use in harsh automotive and industrial environments..
The Hall elements of the sensor CYD8526 are spaced 1.4mm apart, which provides excellent speed and ddirection information for small-geometric targets. Extremely low-drift amplifiers guarantee symmetry between the switches to maintain signal quadrature. An on-chip regulator allows the use of this device over a wide operating voltage range of 3.5V to 24V.
The CYD8526 is available in a 4-pin SIP package and a plastic SOT89B package. The packages are lead (Pb) free, with 100% matte tin leadframe plating.
