DESCRIPTION
The TPA4411 and TPA4411M are stereo headphone
drivers designed to allow the removal of the output
DC-blocking capacitors for reduced component count
and cost. The TPA4411 and TPA4411M are ideal for
small portable electronics where size and cost are
critical design parameters.
APPLICATIONS
Notebook Computers
CD / MP3 Players
Smart Phones
Cellular Phones
PDAs

80-mW DIRECTPATH STEREO HEADPHONE DRIVER
The TPA4411 and TPA4411M are capable of driving
80 mW into a 16-
load at 4.5 V. Both TPA4411 and
TPA4411M have a fixed gain of –1.5 V/V and
headphone outputs that have
±
8-kV IEC ESD
protection. The TPA4411 and TPA4411M have
independent shutdown control for the right and left
audio channels.
