THD+N Tests
THD+N vs. Frequency at –3 dBFS
The above graphs demonstrate that the THD+N specifications for the DAC1 are not frequency
dependent (the variation from 20 Hz to 20 kHz is very slight). Note that at worst case, the
distortion is 109 dB less than the – 3 dBFS test tone (and 112 dB less than the full scale output of
the DAC1). This implies that the distortion created by the DAC1 should be below the threshold of
hearing unless playback levels exceed 112 dB peak SPL. Distortion should still be well masked at
higher playback levels.
