General Description  
Output power at 0.1% THD+N  
at 1kHz into 32  
75mW (typ)  
The LM4908 is a dual audio power amplifier capable of  
delivering 120mW per channel of continuous average power  
into a 16load with 0.1% (THD+N) from a 5V power supply.  
Features  
Boomer audio power amplifiers were designed specifically to  
provide high quality output power with a minimal amount of  
external components using surface mount packaging. Since  
the LM4908 does not require bootstrap capacitors or snub-  
ber networks, it is optimally suited for low-power portable  
systems.  
n Up to 10kV ESD protection on all pins  
n MSOP, SOP, and LLP surface mount packaging  
n Switch on/off click suppression  
n Excellent power supply ripple rejection  
n Unity-gain stable  
The unity-gain stable LM4908 can be configured by external  
gain-setting resistors.  
n Minimum external components
