DESCRIPTION
The DG2718 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 DG2718 is ideal for
portable and battery powered applications requiring high
performance and efficient use of board space.
The DG2718 is built on Vishay Siliconix’s low voltage process. An
epitaxial layer prevents latchup. Break-before-make is
guaranteed.
The switch conducts equally well in both directions when on,
and blocks up to the power supply level when off.
