Note 3. Measured by AD725C (SHIBASOKU). Averaging mode.
In case of VDD=3.0V,
THD+N: -89dB
DR: 96dB (A-weight)
S/N: 97dB (A-weight)
Note 4. Full-scale voltage (0dB). Output voltage scales with the voltage of VREF.
AOUT (typ.@0dB)=1.10Vpp*VREF/2.
Note 5. In case of power-down mode, all digital input pins including clock pins (MCLK,BICK and LRCK) are held VDD
or VSS.
