General Description
The AS5043 is a contactless angular measurement system-on-chip,
combining integrated Hall elements, analog front end and digital signal
processing in a single device.
It computes the mechanical angle of a simple 2 pole diametrically
magnetized magnet that is placed either above or below the device.
The AS5043 has a resolution of 10bits, providing 1024 absolute
positions. Furthermore, an analog output proportional to the angle is
available.
The AS5043 can be configured to specific customer requirements by
programming a one time programmable (OTP) register. An internal
voltage regulator allows the AS5043 to operate from either 3.3 V or 5 V
supplies.

The AS5043 Demoboard
The AS5043 demoboard is a complete rotary encoder system with built-in microcontroller, USB interface, 4-digit 7-segment
display and Magnitude output LED. The board is USB powered or externally supplied for standalone operation. Dimensions:
72mm x 54mm (2.82 x 2.13 inch).

Programming
The demoboard also supports external circuits using the AS5043, such as the AS5043 adapter PCB (as shown below) or
any other AS5043 customer application. These are connected to the demoboard and can be displayed, modified or
permanently programmed using the AS5043 Demo Software.
