The cut-off frequency of Headphone-amp output depends on the external resistor and capacitor used. Table 10 shows the
cut off frequency and the output power for various resistor/capacitor combinations. The headphone impedance R
L
is 16
.
Output powers are shown at HVDD = 2.4, 3.0 and 3.3V. The output voltage of headphone is 0.47 x VDD (Vpp)
@
4.8dBFS.
