DESCRIPTION

The DG401/403/405 monolithic analog switches were

designed to provide precision, high performance switching of

analog signals. Combining low power (0.35 µW, typ) with

suited for portable and battery powered industrial and

military applications.

Built on the Vishay Siliconix proprietary high-voltage

silicon-gate process to achieve high voltage rating and

superior switch on/off performance, break-before-make is

guaranteed for the SPDT configurations. 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. On-

resistance is very flat over the full ± 15 V analog range,

rivaling JFET performance without the inherent dynamic

range limitations.

The three devices in this series are differentiated by the type

of switch action as shown in the functional block diagrams.
