AS5046 Datasheet | austriamicrosystems AG

Description The AS5046 is a contactless magnetic angle encoder for accurate measurement up to 360°. It is a system-on-chip, bining integrated Hall elements, analog front end and digital signal processing in a single device. The AS5046 provides a digital serial 12-bit as well as a programmable 10-bit ratiometric analog output that is directly proportional to the angle of a magnet, rotating over the chip. In addition, the serial interface enables a user configurable arrangement of the Hall array and allows access to each individual Sensor of the Hall Array. The AS5046 also provides high resolution information of the magnetic field strength, respectively the vertical distance of the magnet, thus adding excellent state-ofhealth information of the overall system. An internal voltage regulator allows operation of the AS5046 from 3.3V or 5.0V supplies.
