DG2799 Vishay Siliconix Low Voltage, Low On-Resistance, Dual DPDT Analog Switch DESCRIPTION The DG2799 is a dual double-pole/double-throw monolithic CMOS analog switch designed for high performance switching of analog signals. Combining low power, high speed, low on-resistance and small physical size, the DG2799 is ideal for portable and battery powered applications requiring high performance and efficient use of board space. The DG2799 is built on Vishay Siliconix’s low voltage process. An epitaxial layer prevents latchup. Break-beforemake is guaranteed. The switch conducts equally well in both directions when on, and blocks up to the power supply level when off. As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with the lead (Pb)-free device terminations. For analog switching products manufactured in QFN packages, the lead (Pb)-free “-E3/E4” only suffix is being used as a designator. Lead (Pb)free QFN products purchased at any time will have either a nickel-palladium-gold device termination or a 100 % matte tin device termination. The different lead (Pb)-free materials are interchangeable and meet all JEDEC standards for reflow and MSL rating.

Typical values are for design aid only, not guaranteed nor subject to production testing. d. Guarantee by design, not subjected to production test. e. VIN = input voltage to perform proper function. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. www.vishay.com 4 Document Number: 72922 S-52336–Rev.
