FEATURES  
DESCRIPTION  
The LM4929 is an stereo audio power amplifier  
capable of delivering 40mW per channel of  
continuous average power into a 16load or 25mW  
per channel into a 32load at 1% THD+N from a 3V  
power supply.  
23  
OCL outputs — No DC Blocking Capacitors  
External Gain-Setting Capability  
Available in Space-Saving VSSOP Package  
Ultra Low Current Shutdown Mode  
2V - 5.5V Operation  
Boomer audio power amplifiers were designed  
specifically to provide high quality output power with a  
minimal amount of external components. Since the  
LM4929 does not require bootstrap capacitors or  
snubber networks, it is optimally suited for low-power  
portable systems. The LM4929 is configured for OCL  
(Output Capacitor-Less) outputs, operating with no  
DC blocking capacitors on the outputs.  
Ultra Low Noise  
APPLICATIONS  
Portable CD players  
PDAs  
Portable Electronics Devices  
The LM4929 features a low-power consumption  
shutdown mode with  
Additionally, the LM4929 features an internal thermal  
shutdown protection mechanism.
