EARPHONE USE
Class-D output can be used to drive earphone. However to avoid high power to overdrive
earphone and to prevent human ear to accidentally be hurt, a resistor has to be put in series
with the earphone speaker. Typically a resistor of 330 ohms is adequate for this purpose.
Since stereo earphone can not have BTL configuration, one end of BTL signals can be used
as SE (single-ended) output.

Over temperature protection
A temperature sensor is built in the device to detect the temperature inside the device. When
a high temperature around 145
o
C and above is detected the switching output signals are
disabled to protect the device from over temperature. Automatic recovery circuit enables the
device to come back to normal operation when the internal temperature of the device is below
around 120
o
C.
