Notes: VIL = 0.8V, VIH = 2.4V
Analog Frequency Response has ± 1dB limits
SNR of rms output level with 1 KHz full-scale input to rms output level with all zeros into digital input
Measured "A wtd" over a 20 Hz ~ 20 KHz bandwidth (AES17-1991 Idle Channel Noise or EIAJ CP-307 SNR)
THD: 0dB gain, 20 KHz BW, Fs = 48 KHz
A/D & D/A Frequency Response has ± 0.25 dB 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 = 28.8 KHz ~ 100 KHz, with
respect to 1 Vrms DAC output
