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.

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

max (where θmax is

the maximum angle) by

λ, where λ= (360 - θ

max)/2.
