AS5601 Adapter Board

6.3.2 Hysteresis

A 1 to 3 LSB hysteresis of the 12-bit resolution can be enabled.

6.3.3 Slow Filter

The slow filter allows improving the output noise. The default setting for the Slow Filter is 16x and
can be reduced for faster response.

6.3.4 Fast Filter

The fast filter is active by selecting a Fast Filter Threshold. If the output value remains below the
threshold, the output noise is defined by the slow filter setting. When exceeding the threshold, the
output noise is defined from the fast filter for fast output response. The output noise is again defined
by the slow filter as soon as the output stays in the threshold again.

6.3.5 Watchdog

If the watchdog is active, the AS5601 automatically enters Low Power Mode 3 after one minute if
the output value stays within a threshold of 4 LSB.
