Figure 27 Speaker Output Connection (INV = 1)
The right channel is inverted by setting the INV bit, so that the signal across the loudspeaker is the
sum of left and right channels.
COMBINED HEADSET / BTL EAR SPEAKER
In smartphone applications with a loudspeaker and separate ear speaker (receiver), a BTL ear
speaker can be connected at the OUT3 pin, as shown below.

Figure 28 Combined Headset / BTL Ear Speaker (OUT3SRC = 00)
The ear speaker and the headset play the same signal. Whenever the headset is plugged in, the
headphone outputs are enabled and OUT3 disabled. When the headset is not plugged in, OUT3 is
enabled (see “Jack Insertion and Auto-Switching”)
COMBINED HEADSET / SINGLE-ENDED EAR SPEAKER
Instead of a BTL ear speaker, a single-ended ear speaker can also be used, as shown below.
