Notes:
1.
The ratio of the rms output level with 1kHz full scale input to the rms output level with all zeros into the digital input. Measured “A wtd”
over a 20Hz to a 20kHz bandwidth. (AES17-1991 Idle Channel Noise or EIAJ CP-307 Signal-to-noise Ratio).
2.
Stop Band rejection determines filter requirements. Out-of-Band rejection determines audible noise.
3.
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.
