FEATURES  
DESCRIPTION  
The LM4674A is a single supply, high efficiency,  
2.5W/channel, filterless switching audio amplifier. A  
low noise PWM architecture eliminates the output  
filter, reducing external component count, board area  
consumption, system cost, and simplifying design.

Output Short Circuit Protection  
Stereo Class D Operation  
No Output Filter Required  
Logic Selectable Gain  
Independent Shutdown Control  
Minimum External Components  
Click and Pop Suppression  
Micro-Power Shutdown  
The LM4674A is designed to meet the demands of  
mobile phones and other portable communication  
devices. Operating from a single 5V supply, the  
device is capable of delivering 2.5W/channel of  
continuous output power to a 4load with less than  
10% THD+N. Flexible power supply requirements  
allow operation from 2.4V to 5.5V.  
Available in Space-Saving 2mm x 2mm x  
0.6mm DSBGA Package  
The LM4674A features high efficiency compared to  
conventional Class AB amplifiers. When driving an  
8speaker from a 3.6V supply, the device features  
85% efficiency at PO = 500mW. Four gain options are  
pin selectable through the GAIN0 and GAIN1 pins.  
APPLICATIONS  
Mobile Phones  
PDAs  
Laptops  
Output short circuit protection prevents the device  
from being damaged during fault conditions. Superior  
click and pop suppression eliminates audible  
transients on power-up/down and during shutdown.  
Independent left/right shutdown controls maximizes  
power savings in mixed mono/stereo applications.  
KEY SPECIFICATIONS
