Hi , This device as well as it's prececessor (UDC90120) do not mention any anti aliasing filter for voltage measurements built inside teh chip or required externally . Monitored voltages will have 5-10 % noise due to switched mode power supplies, what is the rationale behind ommiting this type of filter ?
If it is however implemented what is teh characteristic of this filter ( cut off frequency, order , phase shift, pass band ripple)
Regards
Sebastian
