UTC A2804
LINEAR INTEGRATED CIRCUIT
ZERO VOLTAGE SWITCH
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
*Easy operation either through the AC line or a DC
supply.
*Supply voltage control.
*Very few external components.
*Symmetrical burst control-No DC current components in
the load circuit
*Negative output current pulse up to 250mA-short circuit
protection.
*Reference voltage output
DIP-8
*Pb-free plating product number: A2804L
