DESCRIPTION  
•
•
Short-Circuit and Thermal Protection  
Pop Reduction Circuitry  
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  
The TPA4411 and TPA4411M are capable of driving  
80 mW into a 16-Ω 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.  
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.
