Notes:
4. The ratio of the rms value of the signal to the rms sum of all the spectral components less than 20kHz bandwidth,
including distortion components.
5. S/(N+D) which is measured with an input signal of -60dB below full-scale.
6. This value is the full scale(0dB) of the input voltage. Input voltage is proportional to VA. (Vin=0.6xVA)
7. 9kW(typ) and 6kW(min) at fs=96kHz.
8. PSR is applied to VA,VD with 1kHz, 50mVpp.
9. VA=16mA(typ); VD=8mA(typ)@48kHz&5V, 5mA(typ)@48kHz&3V, 14mA(typ)@96kHz&5V.
