DG2799
Voltage, On-Resistance, Dual DPDT Analog Switch
DG2799 dual double-pole/double-throw monolithic CMOS analog switch designed high performance switching analog signals. Combining power, high speed, on-resistance small physical size, DG2799 ideal portable battery powered applications requiring high performance efficient board space. DG2799 built Vishay Siliconix's voltage process. epitaxial layer prevents latchup. Break-beforemake guaranteed. switch conducts equally well both directions when blocks power supply level when off. committed partner community environment, Vishay Siliconix manufactures this product with lead (Pb)-free device terminations. analog switching products manufactured packages, lead (Pb)-free "-E3/E4" only suffix being used designator. Lead (Pb)free products purchased time will have either nickel-palladium-gold device termination matte device termination. different lead (Pb)-free materials interchangeable meet JEDEC standards reflow rating.
