A2804L-S08-R 数据手册
UNISONIC TECHNOLOGIES CO., LTD A2804 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. SOP-8 LINEAR INTEGRATED CIRCUIT 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 D IP-8 *Pb-free plating product number: A2804L ORDERING INFORMATION Ordering Number Normal Lead Free Plating A2804-D08-T A2804L-D08-T A2804-S08-R A2804L-S08-R A2804-S08-T A2804L-S08-T Package DIP-8 SOP-8 SOP-8 Packing Tube Tape Reel Tube A2804L-D08-T (1)Packing Type (2)Package Type (3)Lead Plating (1) T: Tube, R: Tape Reel (2) D08: DIP-8, S08: SOP-8 (3) L: Lead Free Plating, Blank: Pb/Sn www.unisonic.com.tw Copyright © 2005 Unisonic Technologies Co., Ltd 1 of 5 QW-R121-004,B A2804 PIN CONFIGURATION LINEAR INTEGRATED CIRCUIT REF.
