Symbol
Analog Frequency Response has ±1dB limits
SNR (measured as THD+N) of rms output level with 1kHz full-scale input to rms output level with all zeros into digital input
Measured “A wtd” over a 20Hz ~ 20kHz bandwidth (AES17-1991 Idle Channel Noise or EIAJ CP-307 SNR)
THD: 0dB gain, 20kHz BW, Fs = 48kHz, -3dB “large” signal
A/D and D/A Frequency Response has ±0.25dB limits
Stop Band Rejection determines filter requirements
Out-of-Band rejection determines audible noise
Integrated Out-of-band noise generated by DAC during normal PCM audio playback over: BW = 28.8kHz~100kHz, with
