The DG411 series monolithic CMOS analog switches are
drop-in replacements for the popular DG211 and DG212
series devices. They include four independent single pole
throw (SPST) analog switches, and TTL and CMOS
compatible digital inputs.

and faster switch time (t <175ns) compared to the DG211
or DG212. Charge injection has been reduced, simplifying
sample and hold applications.

• Upgrade from DG211, DG212
• TTL, CMOS Compatible
• Single or Split Supply Operation
• Pb-Free Plus Anneal Available (RoHS Compliant)
The improvements in the DG411 series are made possible
by using a high voltage silicon-gate process. An epitaxial
layer prevents the latch-up associated with older CMOS
technologies. The 44V maximum voltage range permits

single-ended from +5V to 44V, or split from ±5V to ±20V.
• Battery Operated Systems
• Data Acquisition
The four switches are bilateral, equally matched for AC or
bidirectional signals. The ON-resistance variation with analog
signals is quite low over a ±15V analog input range. The
switches in the DG411 and DG412 are identical, differing only
in the polarity of the selection logic. Two of the switches in the
DG413 (#2 and #3) use the logic of the DG211 and DG411
(i.e., a logic “0” turns the switch ON) and the other two
switches use DG212 and DG412 positive logic. This permits
independent control of turn-on and turn-off times for SPDT
configurations, permitting “break-before-make” or “make-
before-break” operation with a minimum of external logic.
