Note 4 : The ratio of the rms value of the signal to the sum of all other spectral components up to 20kHz

except for the signal (included harmonic component, excluded DC component, analog input

signal is -0.5dB). Inversed of THD+N.

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 100dB(typ.). When using CCIR-ARM filter,

S/N is 100dB(typ.).

Note 7 : Almost no current is supplied from VB pin.
