I just measure the output voltage of PCM1794 ezDAC will the
oscilloscope,
R27,28,33,24 are 1.5K Ohms
R25,26,31,32 are 100 Ohms
and R23,24,29,30 are 25 Ohms
The result is about 4.9V "peak to peak", which means it is about 1.7V
RMS.
The value is lower than my soundcards analog output:
Prodigy 7.1XT: 5.9V peak-to-peak
X-fi extremmusic: 6.6V peak-to-peak
However, this value is comparable to standard stationary CD players
output which is 2V RMS/ 5V ptp
