Note 4. Measured by Audio Precision (System Two). Refer to the evaluation board manual.
Note 5. 98dB for 16bit input data
Note 6. S/N does not depend on input data size.
Note 7. Full-scale voltage (0dB). Output voltage is proportional to the voltage of VDD,
AOUT (typ.@0dB) = 2.12Vrms × VDD/5.
Note 8. In case of driving capacitive load, inset a resistor between the output pin and the capacitive load.
Note 9. The current into VDD and CVDD.
Note 10. All digital inputs including clock pins (MCLK, BICK and LRCK) are fixed to VSS or VDD
