Performance Graphs
The following graphs apply to both DAC1 and DAC1 USB converters:
Frequency Response Tests
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. The
amplitude response is down by only 0.22 dB at 20 kHz. The bass response extends well below the
10-Hz limitation of the measurement equipment.
