Notes: 4. Measured by Audio Precision (System Two) or UPD. Refer to the evaluation board manual.
5. 100dB at 16bit data.
6. S/N does not depend on input bit length.
7. Full-scale voltage (0dB). Output voltage scales with the voltage of VREF,
AOUT (typ.@0dB)=(AOUT+)-(AOUT-)=±3.2Vpp × VREF/5.
8. For AC-load. 4kΩ for DC-load.
9. All digital inputs including clock pins (MCLK, BICK and LRCK) are held DVDD or DVSS.
