DESCRIPTION
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 (r
3.0 W @ 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.
BENEFITS
D Reduced Power Consumption
D Simple Logic Interface
D High Accuracy
D Reduce Board Space
DS(on)
Vishay Siliconix
APPLICATIONS
D Cellular Phones
D Communication Systems
D Portable Test Equipment
D Battery Operated Systems
D Sample and Hold Circuits
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.
