Description
The DG200A is a dual, single-pole, single-throw analog
switch designed to provide general purpose switching of
analog signals. This device is ideally suited for designs
requiring a wide analog voltage range coupled with low
on-resistance.
The DG200A is designed on Siliconix’ improved PLUS-40
CMOS process. An epitaxial layer prevents latchup.
Each switch conducts equally well in both directions when
on, and blocks up to 30 V peak-to-peak when off. In the on
condition, this bi-directional switch introduces no offset
voltage of its own.
