DG2799  
Vishay Siliconix  
Low Voltage, Low On-Resistance, Dual DPDT Analog Switch  
DESCRIPTION  
FEATURES  
Low Voltage Operation (1.65 V to 4.3 V)  
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.  
Low On-Resistance - rON: 0.25 @ 2.7 V  
Fast Switching:tON = 28 ns  
tOFF = 17 ns  
QFN-16 (3 x 3) Package  
Latch-Up Current > 300 mA (JESD78)  
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.  
BENEFITS  
Reduced Power Consumption  
High Accuracy  
Reduce Board Space  
TTL/1.8-V Logic Compatible  
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.
