Note: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. 40kΩ(typ) and 25kΩ(min) at fs=96kHz.
8. PSR is applied to VA,VD with 1kHz, 50mVpp.
9. VA=11mA; VD=3mA@48kHz,5V, 1.5mA@48kHz,3V, 6mA@96kHz,5V (typ).
