Hello,
I tried LPF in Scan _ADC_v3_10 in various ways.
In conclusion, the minimum corner freq(kHz) was 0.8kHz like below.
We could not set lower frequency than 0.8kHz. Is this correct?
Best regards,
Yocchi

Hi Yocchi-san,
40 Hz corner frequency is not achievable using UAB filter due to the minimum sample rate requirement (50 kHz) and maximum allowed OSR (200). The warning in your previous screen shot is due to achieved corner frequency using discrete cap values is greater than 5% from the desired value. Setting the corner frequency to 0.44 kHz fits within 5% margin as below.
Thanks,
Dinesh
