NXP Semiconductors
Headphone connection
A headphone can be connected to the amplifier using two
coupling capacitors for each channel. The common
GND pin of the headphone is connected to the ground of
the amplifier (see Fig.13). In this case the BTL/SE pin must
be either at a logic HIGH level or not connected at all.
The two coupling capacitors can be omitted if it is allowed
to connect the common GND pin of the headphone jack
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
QUALITY SPECIFICATION
In accordance with “SNW-FQ-611-E”.

not to ground, but to a voltage level of
the application diagram. In this case the BTL/SE pin must
be either at a logic LOW level or connected to ground.
If the BTL/SE pin is at a LOW level, the power amplifier for
the positive loudspeaker terminal is always in mute
condition.
