DG411, DG412, DG413

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 (<35

Ω)

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

single-ended from +5V to 44V, 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 (#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.
