DESCRIPTION
The DG200A_MIL 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_MIL is designed on Vishay 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.
