DESCRIPTION

The DG401, DG403, DG405 monolithic analog switches

were designed to provide precision, high performance

switching of analog signals. Combining low power (0.35 μW,

typ.) with high speed (tON: 75 ns, typ.), the DG401 series is

ideally 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. Onresistance

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.
