AS5600 − Register Description
Analog Output Mode
By default, the AS5600 output stage is configured as analog
ratiometric output. The Digital to Analog Converter (DAC) has
12-bit resolution. In default mode, the lower reference voltage
for the DAC is GND, while the upper reference voltage is VDD.
The output voltage on the OUT pin is ratiometric between GND
and VDD.
The maximum angular range can be programmed from
18 degrees to 360 degrees. The default range is 360 degrees.
As shown below, if the range is 360 degrees, to avoid
discontinuity points exactly at the limit of the range, a 10-LSB
hysteresis is applied. This hysteresis suppresses toggling the
OUT pin when the magnet is close to zero or 360 degrees.

Output Characteristic Over a 360° Full-Turn Revolution
The AS5600 supports programming both a zero angle as well
as the maximum angular range. As shown in Figure 28, reducing
the maximum angular range pushes the non-discontinuity
points to the edges, away from the 0 and θ
max
(where θ
max
is
the maximum angle) by λ, where λ= (360 - θ
max
)/2.
