Graph Plot 10 - THD+N vs. FREQUENCY 80 kHz
The analog output stages on the DAC2 have high slew rates and are capable of maintaining low
THD levels at high frequencies even when driven to 0 dBFS. Note that there is almost no rise in
THD+N with frequency, even when operating at maximum output levels.
