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.
