Description  
The TS472 is a differential-input microphone  
preamplifier optimized for high-performance, PDA  
and notebook audio systems.  
This device features an adjustable gain from 0dB  
to 40dB with excellent power-supply and  
common-mode rejection ratios. In addition, the  
TS472 has a very low-noise microphone bias  
generator of 2V.  
Pin Connection (top view)  
It also includes a complete shutdown function,  
with active low standby mode.  
Applications  
Video and photo cameras with sound input  
Sound acquisition & voice recognition  
Video conference systems  
Notebook computers and PDAs
