The test conditions for the THD values in the graph of Figure 66 are a ±3-V reference input on the BP-DAC11001EVM, and an external 3x gain at the DAC output. The THD calculation considers 11 harmonics; the even harmonics are omitted. When two DACs are used in a differential output mode, the even harmonics are cancelled to a large extent. Figure 66 shows an ideal scenario, when the even harmonics are completely cancelled out.
