Linear Position Sensor ICs

Allegro offers a variety of linear position sensor ICs to meet a wide range of automotive, industrial and consumer position sensor application needs. Allegro’s Hall-effect linear position sensor ICs enable highly accurate contactless sensing of either magnet or ferrous objects, and depending upon the specific linear sensor, can be factory and/or customer programmed. Allegro’s linear position sensor IC portfolio supports analog, PWM and standard digital output protocols such as SENT (Single Edge Nibble Transmission) and are available in various bandwidth, resolution and accuracy options. They are offered in ultra-small packages, including the SOT23-W surface mount package and the 1 mm thick single in-line KT package.
