The AS5030 is a contactless magnetic rotary encoder for accurate angular measurement over a full turn of 360°. It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device.
The AS5030 is a contactless magnetic rotary encoder that provides absolute angular position over a full 360° turn. It integrates Hall elements, an analog front‑end and digital signal processing in a single SOC, delivering 8‑bit resolution (256 positions) via PWM or serial bit‑stream, and also reports magnetic field strength as a 6‑bit code. The device is suited for harsh environments, battery‑operated equipment, robotics, motor control and human‑machine interfaces.
Key features include a TSSOP‑16 package with a detailed pin‑out, configurable 1‑wire PWM, 2‑wire or 3‑wire serial interfaces, programmable zero‑position, high‑speed operation up to 30 000 rpm, low power‑down modes, and a wide magnetic field input range (20‑80 mT). The handbook provides full specifications, magnet requirements, programming details, and timing diagrams for integration.
