Hi all,

The value of Digital Filter Monitoring Time when fscantyp is 100k is as follows.

Is it correct that this value is multiplied by 100k/125K when fscantyp is 125kHz?

@MS_19060803 -san,

Yes this is correct, the effective filter times will scale with frequency. Doubling the frequency will lead to half of the filter times – your formula indicates the situation correctly!

Ex)
tFILT01_100k : 1ms for 100kHz
tFILT01_125k : 0.8ms for 125kHz, tFILT01_100k x (100kHz / 125kHz)

Thanks,
