10-W into an 8-Ω Load at 10% THD+N From a  
12-V Supply  
The TPA3111D1 is a 10-W efficient, Class-D audio  
power amplifier for driving a bridge tied speaker.  
Advanced EMI Suppresion Technology enables the  
use of inexpensive ferrite bead filters at the outputs  
while meeting EMC requirements. SpeakerGuard™  
speaker protection system includes an adjustable  
7-W into an 4-Ω Load at 10% THD+N From a  
8-V Supply  
94% Efficient Class-D Operation into 8-Ω Load  
Eliminates Need for Heat Sinks  
Wide Supply Voltage Range Allows Operation  
from 8 to 26 V  
power limiter and  
a DC detection circuit. The  
adjustable power limiter allows the user to set a  
"virtual" voltage rail lower than the chip supply to limit  
the amount of current through the speaker. The DC  
detect circuit measures the frequency and amplitude  
of the PWM signal and shuts off the output stage if  
the input capacitors are damaged or shorts exist on  
the inputs.

•
Filter-Free Operation  
SpeakerGuard™ Speaker Protection Includes  
Adjustable Power Limiter plus DC Protection  
•
•
Flow Through Pin Out Facilitates Easy Board  
Layout  
Robust Pin-to-Pin Short Circuit Protection and  
Thermal Protection with Auto-Recovery Option  
The TPA3111D1 can drive a mono speaker as low as  
4Ω. The high efficiency of the TPA3111D1, > 90%,  
eliminates the need for an external heat sink when  
playing music.  
•
•
•
Excellent THD+N/ Pop Free Performance  
Four Selectable, Fixed Gain Settings  
Differential Inputs  
The outputs are fully protected against shorts to  
GND, VCC, and output-to-output. The short-circuit  
protection and thermal protection includes an  
auto-recovery feature.
