DESCRIPTION
The TPA4411 is a stereo headphone driver designed
to allow the removal of the output dc-blocking capaci-
tors for reduced component count and cost. The
TPA4411 is ideal for small portable electronics where
size and cost are critical design parameters.

80-mW CAPLESS STEREO HEADPHONE DRIVER
The TPA4411 is capable of driving 80 mW into a
16-
load at 4.5 V. The TPA4411 has a fixed gain of
-1.5 V/V and headphone outputs have
±
8-kV IEC
ESD protection. The TPA4411 has independent shut-
down control for the right and left audio channels.
The TPA4411 is available in a 20-pin, 4 mm
×
4 mm
ThinQFN package.
