LM48903  
Stereo Class D Spatial Array  
General Description  
Features  
The LM48903 is a stereo Class D amplifier that utilizes TI’s  
proprietary spatial sound processor to create an enhanced  
sound stage for portable multimedia devices. The Class D  
output stages feature National’s edge rate control (ERC)  
PWM architecture that significantly reduces RF emissions  
while preserving audio quality and efficiency.  
The LM48903’s flexible I2S interface is compatible with stan-  
dard serial audio interfaces. A stereo differential-input ADC  
gives the device the ability to process analog stereo audio  
signals.  
The LM48903 is configured through an I2C compatible inter-  
face and is capable of delivering 1.7W/channel of continuous  
output power into an 8load with less than 10% THD+N.  
Output short circuit and thermal overload protection prevent  
the device from being damaged during fault conditions. Click  
and pop suppression eliminates audible transients on power-  
up/down and during shutdown. The LM48903 is available in  
space saving micro SMD package.
