Note: 3. Measured by AD725C (SHIBASOKU). Averaging mode. Refer to the evaluation board manual.
4.
Full-scale voltage (0dB). Output voltage scales with the voltage of VREF.
AOUT (typ.@0dB)=3.45Vpp*VREF/5.
5. Power Dissipation in the power-down mode is applied with no external clocks
(MCLK, BICK and LRCK held “VDD” or “VSS”).
6. PSR is applied to VDD with 1kHz, 100mVpp. VREF pin is held +5V.
