The analog input level at which the ADC outputs full scale varies according to supply voltage AVDn.
When supply voltage AVDn contains deviation, calculate the maximum input level from (Formula 1) below
and adjust the level with the ADC front-end prefilter, etc., so that the waveform is not clipped at the
minimum voltage.
ADC maximum input level [Vrms] = 1.33 [Vrms]

(Formula 1)

Like the ADC, the DAC conversion gain also varies according to supply voltage AVDn. However, the DAC
has the reverse characteristics of the ADC, so the total gain between the ADC and DAC is constant.
