Graph Plot 12 - THD vs. Frequency - All Outputs

This plot demonstrates that all of the analog outputs on the DAC2 have very similar performance

over the entire audio band. The unbalanced outputs, and the headphone outputs, closely match

the performance of the balanced outputs. Like Graph Plot 11 - EVEN AND ODD THD vs.

FREQUENCY, this plot shows THD (not THD+N).
