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.
