Power Supply Rejection Ratio
Note 8 : The ratio of the rms value of the signal to the sum of all other spectral components up to 40kHz
except for the signal (included harmonic component, excluded DC component, analog input
signal is -0.5dB). Inversed of THD+N.
Note 9 :
S/(N+D) with an input signal of 60dB below full-scale.
Note 10 : These value are measured by 40kHz flat, without A-weighted. When using A-weighted, S/N and
DR are 104dB(typ.).
Note 11 : Almost no current is supplied from VB pin.
