U4030B  
Telephone Speech Circuit  
Description  
The U4030B is an electronic speech circuit for standard designs can improve transmission quality and results in  
and feature telephones. It replaces the hybrid transformer, cost savings through shorter and more flexible design  
earphone and microphone interface and the supply procedures. It reduces the amount of external components  
voltage generation for external components, e.g. dialer or needed. The U4030B uses TEMIC’s reliable bipolar  
microcomputers. Using the U4030B in telephone circuit technology and is offered in a SO20 package.
