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 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.
