Monolithic Quad SPST, CMOS Analog
Switches
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.
These switches feature lower analog ON resistance (<35Ω)
and faster switch time (t
ON
< 175ns) compared to the
DG211 or DG212. Charge injection has been reduced,
simplifying sample and hold applications.
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
controlling 40V
P-P
signals. Power supplies may be
single-ended from +5V to +34V, or split from
±5V
to
±20V.
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 (#1 and #4) 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.
