Power Supply Rejection Ratio
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 99dB(typ.). When using CCIR-ARM filter,
S/N is 99dB(typ.)
Note 7 : Almost no current is supplied from VB pin.
