4. 100dB at 16bit data.
5. S/N does not depend on input bit length.
6. Full-scale voltage (0dB). Output voltage scales with the voltage of VREF,
7. For AC-load. 4k
8. All digital inputs in cluding clock pins (MCLK, BICK and LRCK) are held VDD or VSS.
AOUT (typ.@0dB)=(AOUT+)-(AOUT-)= 2.75Vpp × VREF/5.
