AS5030
8-Bit Programmable High Speed Magnetic Rotary Encoder
1 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.
Data transmission can be configured for 1-wire (PWM), 2-wires
(CLK, DIO) or 3-wires (CLK, DIO, CS).
A software programmable (OTP) zero position simplifies assembly
as the zero position of the magnet does not need to be mechanically
aligned.
A Power Down Mode together with fast startup- and measurement
cycles allows for very low average power consumption and makes
the AS5030 also suitable for battery operated equipment.
