The cut-off frequency of Headphone-amp output depends on the external resistor and capacitor used. Table 33 shows the
cut off frequency and the output power for various resistor/capacitor combinations. The Headphone impedance R
L
is
16
Ω
. Output powers are shown at HVDD = 2.7, 3.0 and 3.3V. The output voltage of Headphone is 0.6 x AVDD (Vpp).
