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 Ω @ 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.

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.
