FEATURES  
DESCRIPTION  
The LM4951A is an audio power amplifier designed  
for applications with supply voltages ranging from  
2.7V up to 9V. The LM4951A is capable of delivering  
1.8W continuous average power with less than 1%  
THD+N into a bridge connected 8load when  
operating from a 7.5VDC power supply.  
23  
Pop & Click Circuitry Eliminates Noise During  
Turn-On and Turn-Off Transitions  
Wide Supply Voltage Range: 2.7V to 9V  
Low Current, Active-Low Shutdown Mode  
Low Quiescent Current  
Boomer™ audio power amplifiers were designed  
specifically to provide high quality output power with a  
minimal amount of external components. The  
LM4951A does not require bootstrap capacitors, or  
snubber circuits.  
Thermal Shutdown Protection  
Short Circuit Protection  
Unity-Gain Stable  
External Gain Configuration Capability  
The LM4951A features a low-power consumption  
active-low shutdown mode. Additionally, the  
LM4951A features an internal thermal shutdown  
protection mechanism and short circuit protection.  
APPLICATIONS  
Portable Devices  
Cell Phones  
The LM4951A contains advanced pop & click circuitry  
that eliminates noises which would otherwise occur  
during turn-on and turn-off transitions.  
Laptop Computers  
Computer Speaker Systems  
MP3 Player Speakers  
The LM4951A is unity-gain stable and can be  
configured by external gain-setting resistors.  
KEY SPECIFICATIONS
