AS5600 − Detailed Description

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.

Figure 32:

Step Response (fast filter off )

For a fast step response and low noise after settling, the fast

filter can be enabled. The fast filter works only if the input

variation is greater than the fast filter threshold, otherwise the

output response is determined only by the slow filter. The fast

filter threshold is programmed with the FTH bits in the “CONF

stays within an error band after two full sampling periods to

settle to the final value determined by the slow filter.
