Description
The DG401/403/405 monolithic analog switches were
designed to provide precision, high performance switching of
analog signals. Combining low power (0.35 mW, typ) with
high speed (t_ON: 100 ns, typ), the DG401 series is ideally
suited for portable and battery powered industrial and military
applications.
Built on the 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.
