DG2037/2038/2039
Vishay Siliconix
Low-Voltage, Low r , Dual SPST Analog Switch
ON
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.

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
The DG2037/2038/2039 are built on Vishay Siliconix’s new
high density low voltage process. An epitaxial layer prevents
latchup.
BENEFITS
