HEADPHONE OUTPUT POWER CHARACTERISTICS
Test conditions (unless otherwise specified): Input test signal is a full-scale 997 Hz sine wave; measurement band-
width is 10 Hz to 20 kHz; Sample Frequency = 48 kHz; test load R
L
= 16
,
C
L
= 10 pF (see
Figure 3
).
Notes:
9.
10. Full-scale output voltage and power is determined by the gain setting, G, in register
“Headphone Analog
Gain (HP_GAIN[2:0])” on page 54
. High gain settings at certain VA and VA_HP supply levels may
cause clipping when the audio signal approaches full-scale, maximum power output, as shown in
Figures 28
-
31 on page 73
.
11. See
Figure 3
. R
L
and C
L
reflect the recommended minimum resistance and maximum capacitance re-
quired for the internal op-amp's stability and signal integrity. In this circuit topology, C
L
will effectively
move the band-limiting pole of the amp in the output stage. Increasing this value beyond the recom-
mended 150 pF can cause the internal op-amp to become unstable.
12. VA_HP 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.
One-half LSB of triangular PDF dither is added to data.
