MA800 Datasheet | Monolithic Power Systems

DESCRIPTION The MA800 is an easy-to-use, magnetic, angle encoder with a digital output designed to replace analogic potentiometers or rotary switches. The MA800 is designed for slow operation such as human-machine interface, manual controls, etc. where the rotating speed remains below 200 rpm. The sensor detects the absolute angular position of a permanent magnet attached to a rotating shaft. The magnet shapes and configurations are very flexible. Typically, the MA800 is used with a diametrically magnetized cylinder of 2 - 8mm in diameter. The MA800 features programmable magnetic field strength thresholds, which allow for the implementation of a push or pull button function. These are output as two logic signals. On-chip non-volatile memory provides storage for the configuration parameters, including the reference zero angle position and magnetic field detection threshold settings.
