DAC FILTER RESPONSES

This series of plots shows the filter response for the entire DAC channel for different signal rates. The

full path, has a nominal gain of 3.01dB (1V input, 1.414V output), this means that the highest nodes in

the 48kHz case are at 47.5dB (rather than below the 50dB specification).
