LM4810  
Dual 105mW Headphone Amplifier with Active-High  
Shutdown Mode  
n THD+N at 1kHz, 70mW continuous average power into  
General Description  
32  
0.1% (typ)  
The LM4810 is a dual audio power amplifier capable of  
delivering 105mW per channel of continuous average power  
into a 16load with 0.1% (THD+N) from a 5V power supply.  
n Shutdown Current  
0.4µA (typ)  
Features  
Boomer audio power amplifiers were designed specifically to  
provide high quality output power with a minimal amount of  
external components. Since the LM4810 does not require  
bootstrap capacitors or snubber networks, it is optimally  
suited for low-power portable systems.  
n Active-high shutdown mode  
n LLP, MSOP, and SO surface mount packaging  
n "Click and Pop" suppression circuitry  
n Low shutdown current  
n No bootstrap capacitors required  
n Unity-gain stable  
The unity-gain stable LM4810 can be configured by external  
gain-setting resistors.  
The LM4810 features an externally controlled, active-high,  
micropower consumption shutdown mode, as well as an  
internal thermal shutdown protection mechanism.  
Applications  
n Cellular Phones  
n Personal Computers  
n Microphone Preamplifier  
n PDA’s  
Key Specifications  
n THD+N at 1kHz, 105mW continuous average power into
