1 / 10 page Vishay Siliconix DG2799 Document Number: 72922 S-52336–Rev. F, 07-Nov-05 www.vishay.com 1 Low Voltage, Low On-Resistance, Dual DPDT Analog Switch FEATURES • Low Voltage Operation (1.65 V to 4.3 V) • Low On-Resistance - rON: 0.25 Ω @ 2.7 V • Fast Switching: tON = 28 ns tOFF = 17 ns • QFN-16 (3 x 3) Package • Latch-Up Current > 300 mA (JESD78) BENEFITS • Reduced Power Consumption • High Accuracy • Reduce Board Space • TTL/1.8-V Logic Compatible • High Bandwidth APPLICATIONS • Cellular Phones • Speaker Headset Switching • Audio and Video Signal Routing • PCMCIA Cards • Battery Operated Systems DESCRIPTION The DG2799 is a dual double-pole/double-throw monolithic CMOS analog switch designed for high performance switch- ing 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 pro- cess. An epitaxial layer prevents latchup. Break-before- make 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 environ- ment, 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.
