Note 5. Measured by Audio Precision (System Two). Refer to the evaluation board manual.
Note 6. 98dB for 16-bit input data
Note 7. S/N does not depend on input data length.
Note 8. Full-scale voltage (0dB). Output voltage is proportional to the voltage of VDD
AOUT (typ.@0dB) = 2Vrms × VDD/3.3.
Note 9. PSRR is applied to VDD and CVDD with 1kHz, 50mVpp.
Note 10. In case of driving capacitive load, inset a resistor between the output pin and the capacitive load.
Note 11. The current into VDD and CVDD.
Note 12. All digital inputs including clock pins (MCLK, BICK and LRCK) are fixed to VSS or VDD.
