DAC1 Performance Curves:
Frequency Response at Fs = 48 kHz
The above graphs show the frequency response of the DAC1 when it is operating at a 48-kHz sample rate. The
top graph shows that the differential phase is better than ± 0.5º at 20 kHz. The bottom graph shows the amplitude
response on a highly expanded 0.05 dB/division scale. Note that the amplitude response is down by only 0.22 dB
at 20 kHz and that the bass response extends well below the 10-Hz limitation of the measurement equipment.
