Notes: 3. Measured by Audio Precision (System Two). Refer to the evaluation board manual.
4. Full-scale voltage (0dB). Output voltage scales with the voltage of VREF,
AOUT (typ@0dB) = 3.4Vpp×VREF/5.
5. All digital inputs including clock pins (MCLK, BICK and LRCK) are held VDD or VSS.
6. PSR is applied to VDD with 1kHz, 100mV. VREF pin is held +5V.
