Precision Monolithic Quad SPST CMOS Analog Switches
DESCRIPTION
The DG411 series of monolithic quad analog switches was
designed to provide high speed, low error switching of
precision analog signals. Combining low power (0.35 µW)
with high speed (t
ON
: 110 ns), the DG411 family is ideally
suited for portable and battery powered industrial and military
applications.
To achieve high-voltage ratings and superior switching
performance, the DG411 series was built on Vishay
Siliconix’s high voltage silicon gate process. An epitaxial
layer prevents latchup.
Each switch conducts equally well in both directions when
on, and blocks input voltages up to the supply levels when
off.
The DG411, DG412 respond to opposite control logic as
shown in the Truth Table. The DG413 has two normally open
and two normally closed switches.
