80-mW/Ch Output Power into 16- at 4.5 V
Independent Right and Left Channel
Shutdown Control
Short-Circuit and Thermal Protection
The TPA4411 and TPA4411M are stereo headphone
Pop Reduction Circuitry
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
Notebook Computers
critical design parameters.
CD / MP3 Players
The TPA4411 and TPA4411M are capable of driving
Smart Phones
80 mW into a 16-
load at 4.5 V. Both TPA4411 and
Cellular Phones
TPA4411M have a fixed gain of –1.5 V/V and
PDAs
headphone outputs that have
±8-kV
IEC
ESD
protection. The TPA4411 and TPA4411M have
independent shutdown control for the right and left
audio channels.
The TPA4411 is available in a 2.18 mm
× 2.18 mm
WCSP and 4 mm
× 4 mm Thin QFN packages. The
TPA4411M is available in a 4 mm
× 4 mm Thin QFN
package. The TPA4411RTJ package is a thermally
optimized
PowerPAD
package
allowing
the
maximum amount of thermal dissipation and the
TPA4411MRTJ is a thermally enhanced PowerPAD
package designed to match competitive package
footprints.
