DG2799 Datasheet

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 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-beforemake 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” 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.
FEATURES
• Low Voltage Operation (1.65 V to 4.3 V)
• Low On-Resistance - rON: 0.25 Ω @ 2.7 V

Notes
a. Signals on NC, NO, or COM or IN exceeding V+ will be clamped by internal diodes. Limit forward diode current to maximum current ratings.
b. All leads welded or soldered to PC Board.
c. Derate 17.3 mW/°C above 70°C
d. Manual soldering with iron is not recommended for leadless components. The QFN is a leadless package. The end of the lead terminal is
exposed copper (not plated) as a result of the singulation process in manufacturing. A solder fillet at the exposed copper lip cannot be guaranteed
and is not required to ensure adequate bottom side solder interconnection.

Notes
a. Room = 25°C, Full = as determined by the operating suffix.
b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
c. Typical values are for design aid only, not guaranteed nor subject to production testing.
d. Guarantee by design, not subjected to production test.
e. VIN = input voltage to perform proper function.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
