OUT2L and OUT2R are designed as a stereo pair and can drive a headphone, a line load or a
loudspeaker amplifier. Each output has an analogue volume control PGA with a gain range of -57dB
to +6dB as shown in Figure 45.
Common mode noise rejection is also possible on the OUT2L and OUT2R outputs, using HPCOM as
the return path. The HPCOM feature must be enabled via the OUT2_FB register field and the
HPCOM connection must be AC coupled to the headphone output. A 4.7uF coupling capacitor is
required between the noisy ground connection the HPCOM pin.
The control register fields for the OUT2L and OUT2R outputs are described in Table 41. The
available output configurations are shown in Section 13.9.3.
