1.Dynamic Range is the ratio of the full scale signal to the noise output with a -60dBFS signal as defined in AES17 as SNR in the
presence of signal and outlined in AES6id, measured “A weighted” over 20 Hz to 20 kHz bandwidth.
2.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).
3.THD+N ratio as defined in AES17 and outlined in AES6id,non-weighted, over 20 Hz to 20 kHz bandwidth.Results at the jack
are dependent on external components and will likely be 1 - 2dB worse.
4.Peak-to-Peak Ripple over Passband meets ± 0.125dB limits, 48 kHz or 44.1 kHz Sample Frequency. 1dB limit.
5.Stop Band rejection determines filter requirements. Out-of-Band rejection determines audible noise.
6.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.
7.Gain drift is the change in analog volume control gain for each step across the supported 0
referenced to the 25
8.± 1dB limits for Line Output & 0 dB gain, at -20dBV
9.Spurious tone rejection is tested with ADC dither enabled and compared to ADC performance without dither.
10.Does not include 32
11.Can be set to 0.5 or 0.8 AVdd.
