Notes: 4 . Measured by AD725C(SHIBASOKU). Averaging mode. Refer to the eva board manual.

5 . The voltage on VREFH pin is held +5V externally.

6 . Full-scale voltage(0dB). Output voltage scales with the voltage of VREH-VREFL.

AOUT(typ.@0dB)=3.4Vpp*(VREFH-VREFL)/5.

7 . Power Dissipation in the power-down mode is applied with no external clocks

(MCLK,BICK,LRCK held "H" or "L").

8 . PSR is applied to AVDD,DVDD with 1kHz, 100mVpp. VREF pin is held +5V.
