General Description
The AS5045 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
magnet may be placed above or below the IC.
The absolute angle measurement provides instant
indication of the magnet’s angular position with a
resolution of 0.0879° = 4096 positions per revolution.
This digital data is available as a serial bit stream and as
a PWM signal.
An internal voltage regulator allows the AS5045 to
operate at either 3.3 V or 5 V supplies
