± 1 dB limits
The ratio of the rms output level with 1 kHz full scale input to the rms output level with all
zeros into the digital input. 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).
0 dB gain, 20 kHz BW, 48 kHz Sample Frequency
± 0.25dB limits
Stop Band rejection determines filter requirements.
audible noise.
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.
