AS5600 − Register Description
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
Register. As shown in Figure 34, the step response stays within
an error band after two full sampling periods to settle to the
final value determined by the slow filter.
