AS5600 − Register Description
Step Response and Filter Settings
The AS5600 has a digital post-processing programmable filter
which can be set in fast or slow modes. The fast filter mode can
be enabled by setting a fast filter threshold in the FTH bits of
the CONF register.
If the fast filter is OFF, the step output response is controlled by
the slow linear filter. The step response of the slow filter is
programmable with the SF bits in the CONF register. Figure 32
shows the tradeoff between delay and noise for the different
SF bit settings.
