LM4906  
1W, Bypass-Capacitor-less Audio Amplifier with Internal  
Selectable Gain  
General Description  
Key Specifications  
The LM4906 is an audio power amplifier primarily designed  
for demanding applications in mobile phones and other por-  
table communication device applications. It is capable of  
delivering 1W of continuous average power to an 8BTL  
load with less than 1% distortion (THD+N) from a +5V power  
supply.

Improved PSRR at 217Hz for +3V  
71dB  
Power Output at +5V, THD+N = 1%, 8Ω  
1.0W (typ)  
Power Output at +3V, THD+N = 1%, 8390mW (typ)  
Total shutdown power supply current 0.1µA (typ)  
The LM4906 is the first National Semiconductor Boomer  
Power Amplifier that does not require an external PSRR  
bypass capacitor. The LM4906 also has an internal select-  
able gain of either 6dB or 12dB. In addition, no output  
coupling capacitors or bootstrap capacitors are required  
which makes the LM4906 ideally suited for cell phone and  
other low voltage portable applications.  
Features  
n Selectable gain of 6dB (2V/V) or 12dB (4V/V)  
n No output or PSRR bypass capacitors required  
n Improved “Click and Pop” suppression circuitry  
n Very fast turn on time: 5ms (typ)  
n Minimum external components  
n 2.6 - 5.5V operation  
The LM4906 contains advanced pop and click circuitry that  
eliminates noise, which would otherwise occur during  
turn-on and turn-off transitions.  
n BTL output can drive capacitive loads  
n Ultra low current shutdown mode (SD Low)  
Boomer audio power amplifiers were designed specifically to  
provide high quality output power with a minimal amount of  
external components. The LM4906 features a low -power  
consumption shutdown mode (the part is enabled by pulling  
the SD pin high). Additionally, the LM4906 features an inter-  
nal thermal shutdown protection mechanism.  
Applications  
n Portable computers  
n Desktop computers  
n Multimedia monitors
