The 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. Each switch conducts equally well in both directions when on, and blocks 30 V peak-to-peak when off. In the on condition, this bi-directional switch introduces no offset voltage of its own.
The DG200A is designed on Vishay Siliconix' improved PLUS-40 CMOS process. An epitaxial layer prevents latchup.

Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing. d. The algebraic convention whereby the most negative value is aminimum and the most positive a maximum, is used in this data sheet. e. Guaranteed by design, not subject to production test. f. VIN = input voltage to perform proper function.
