Note 6. Measured by Audio Precision, System Two. Averaging mode.
Note 7. The voltage on (VREFH1  VREFL1) is held +5V externally.
Note 8. The full scale voltage when applying a 1kHz sine wave (0dB) in PCM mode, or when applying a 1kHz
sine wave (25~75% duty) in DSD mode. Output voltage scales with the voltage of (VREFH1 
VREFL1).
DAC1: AOUT (typ.@0dB) = (AOUT+)  (AOUT) = 2.8Vpp  (VREFH1  VREFL1)/5
Note 9. Regarding Load Resistance, AC load is 2k (min) with a DC cut capacitor. DC load is 2 k (min)
without a DC cut capacitor. The load resistance value is with respect to ground. Analog characteristics
are sensitive to capacitive load that is connected to the output pin. Therefore the capacitive load must
be minimized.
Note 10. In the power down mode. All other digital input pins including clock pins (MCLK, BICK and LRCK)
are held DVSS.
