A2804  
LINEAR INTEGRATED CIRCUIT  
ZERO VOLTAGE SWITCH  
SOP-8  
ꢀ
DESCRIPTION  
The UTC A2804 is a TRIAC controller providing a complete  
solution for temperature controlled electric panel heaters, cookers,  
film processing baths etc.  
Switching occurs at the zero voltage point in order to minimize  
radio frequency interference. The device is suitable for mains-on-line  
operation and requires minimal components.  
ꢀ
FEATURES  
DIP-8  
*Easy operation either through the AC line or a DC supply.  
*Supply voltage control.  
*Very few external components.  
*Pb-free plating product number: A2804L  
*Symmetrical burst control-No DC current components in the load  
circuit  
*Negative output current pulse up to 250mA-short circuit protection.  
*Reference voltage output
