AS5134 3 6 0 St e p P r o g r a m m a b l e H i g h Sp e e d M a g n e t i c R o ta r y E n c o d e r D a ta S he e t 1 General Description The AS5134 is a contactless magnetic rotary encoder for accurate angular measurement over a full turn of 360º. It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device. To measure the angle, only a simple two-pole magnet, rotating over the center of the chip is required. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 8.5 bit = 360 positions per revolution. This digital data is available as a serial bit stream and as a PWM signal.
