DG401, DG403, DG405
Vishay Siliconix
Low-Power, High-Speed CMOS Analog Switches
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 (t_ON: 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. 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.
