Notes: 4. Measured by AD725C(SHIBASOKU). Averaging mode. Refer to the eva board manual.
5. The voltage on VREF pin is held +5V externally.
6. Full-scale voltage(0dB). Output voltage scales with the voltage of VREF pin.
AOUT(typ.@0dB)=2.8Vpp*VREF/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.
