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-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 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”
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.
