DG2037/2038/2039
Vishay Siliconix
Low-Voltage, Low rON, Dual SPST Analog Switch
DESCRIPTION
FEATURES
The DG2037/2038/2039 are dual single-pole/single-throw
monolithic CMOS analog switch designed for high
performance switching of analog signals. Combining low
power, fast switching, low on-resistance (rDS(on): 3.0 Ω at
2.7 V) and small physical size, the DG2037/2038/2039 are
ideal for portable and battery powered applications requiring
high performance and efficient use of board space.

•
•
•
•
•
•
The DG2037/2038/2039 are built on Vishay Siliconix’s new
high density low voltage process. An epitaxial layer prevents
latchup.
Each switch conducts equally well in both directions when
on, and blocks up to the power supply level when off.
Low Voltage Operation (1.8 V to 5.5 V)
Low On-Resistance - rDS(on): 3.0 Ω
Fast Switching - 12 ns
Low Charge Injection - QINJ: 10 pC
Low Power Consumption
TTL/CMOS Compatible
SOT23-8 and MSOP-8 Packages

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, nor subjected to production test.
e. VIN = input voltage to perform proper function.
f. Not production tested.
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.
