HEADPHONE OUTPUT POWER CHARACTERISTICS
Test conditions (unless otherwise specified): Input test signal is a full-scale 997 Hz sine wave; Sample Frequency = 48 kHz;
Measurement Bandwidth is 20 Hz to 20 kHz; Test load RL = 16 Ω, CL = 10 pF (see Figure 2); “Required Initialization Settings”
on page 37 written on power up.

11. VHP settings lower than VA reduces the headroom of the headphone amplifier. As a result, the DAC
may not achieve the full THD+N performance at full-scale output voltage and power.
