DESCRIPTION
The DG2003/2004/2005 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
DS(on)
: 1.2
W)
and
small physical size (MSOP-8), the DG2003/2004/2005 are
ideal for portable and battery powered applications requiring
high performance and efficient use of board space.
The DG2003/2004/2005 are built on Vishay Siliconix鈥檚 low
voltage JI2 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.
