(Ta=25 C; VA,VD,VB=5.0V; fs=48kHz; 20bit; Input signal frequency=1kHz,
Note 4 : The ratio of the rms value of the signal to the sum of all other spectral components up to 20kHz
Note 5 : S/(N+D) with an input signal of 60dB below full-scale.
Note 6 : When using only 20kHzLPF, S/N and DR are 99dB(typ.). When using CCIR-ARM filter,
Note 7 : Almost no current is supplied from VB pin.
