FEATURES  
DESCRIPTION  
(1)  
The LM4864 is a bridged audio power amplifier  
capable of delivering 725mW of continuous average  
power into an 8Ω load with 1% THD+N from a 5V  
power supply.  
23  
•
VSSOP, SOIC, PDIP , and WSON Packaging  
•
No Output Coupling Capacitors, Bootstrap  
Capacitors, or Snubber Circuits are Necessary  
•
•
•
Thermal Shutdown Protection Circuitry  
Unity-Gain Stable  
Boomer® audio power amplifiers were designed  
specifically to provide high quality output power from  
a low supply voltage while requiring a minimal  
amount of external components. Since the LM4864  
does not require output coupling capacitors, bootstrap  
capacitors or snubber networks, it is optimally suited  
for low-power portable applications.  
External Gain Configuration Capability  
APPLICATIONS  
•
•
•
Cellular phones  
Personal computers  
General purpose audio  
The LM4864 features an externally controlled, low  
power consumption shutdown mode, and thermal  
shutdown protection.  
KEY SPECIFICATIONS  
The closed loop response of the unity-gain stable  
LM4864 can be configured by external gain-setting  
resistors. The device is available in multiple package  
types to suit various applications.

(1) Not recommended for new designs. Contact TI Audio  
Marketing.  
(2) The DGK0008BA package is thermally limited to 595 mW of  
power dissipation at room temperature. Referring to Figure 21  
in Typical Performance Characteristics, the power dissipation  
limitation for the package occurs at 300 mW of output power.  
This package limitation is based on 25°C ambient  
temperature and θJA = 210°C. For higher output power  
possibilities refer to POWER DISSIPATION.
