General Description
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.
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 bit = 256 positions per revolution. This digital data is available as a serial bit stream and as a PWM signal.
In addition to the angle information, the strength of the magnetic field is also available as a 6-bit code.

Key Features
■360° contactless angular position encoding
■Two digital 8-bit absolute outputs:
    - Serial interface
    - Pulse width modulated (PWM) output
■User programmable zero position
■Direct measurement of magnetic field strength allows exact determination of vertical magnet distance
■Serial read-out of multiple interconnected AS5030 devices using daisy chain mode
■Wide magnetic field input range: 20 ~ 80mT
■Wide temperature range: -40°C to +125°C
■Small Pb-free package: TSSOP 16

Applications
    The AS5030 is suitable for Contactless rotary position sensing, Rotary switches (human machine interface), AC/DC motor position control, Robotics and Encoder for battery operated equipment.
