2. ± 3dB limits for Line Output & 0 dB gain, at -20dBV
3. Amplitude of THD+N, measured with A-weighting filter, over 20 Hz to 20 kHz bandwidth.
4. Ratio of Full Scale signal to idle channel noise output is measured “A weighted” over a 20 Hz to a 20 kHz bandwidth.
(AES17-1991 Idle Channel Noise or EIAJ CP-307 Signal-to-noise Ratio).
5. Peak-to-Peak Ripple over Passband meets ± 0.25dB limits, 48 kHz Sample Frequency.
6. Stop Band rejection determines filter requirements. Out-of-Band rejection determines audible noise.
7. The integrated Out-of-Band noise generated by the DAC process, during normal PCM audio playback, over a bandwidth
28.8 to 100 kHz, with respect to a 1 Vrms DAC output.
8. Can be set to 0.5 or 0.8 AVdd.
9. Analog mixer disabled. See Figure 2
10. Didd= Didd_Core + Didd_IO (with all converters enabled and no playback)
11. Current reduction by disabling.
