GENERAL DESCRIPTION
The ADG1411/ADG1412/ADG1413 are monolithic complemen-
tary metal-oxide semiconductor (CMOS) devices containing
four independently selectable switches designed on an iCMOS®
process. iCMOS (industrial CMOS) is a modular manufacturing
process combining high voltage CMOS and bipolar technologies.
It enables the development of a wide range of high performance
analog ICs capable of 33 V operation in a footprint that no previous
generation of high voltage parts has been able to achieve. Unlike
analog ICs using conventional CMOS processes, iCMOS com-
ponents can tolerate high supply voltages while providing increased
performance, dramatically lower power consumption, and reduced
package size.
The on-resistance profile is very flat over the full analog input
range, ensuring excellent linearity and low distortion when
switching signals.
iCMOS construction ensures ultralow power dissipation,
making the parts ideally suited for portable and battery-
powered instruments.
The ADG1411/ADG1412/ADG1413 contain four independent
single-pole/single-throw (SPST) switches. The ADG1411 and

SWITCHES SHOWN FOR A LOGIC 1 INPUT.
Figure 1.
ADG1412 differ only in that the digital control logic is inverted.
The ADG1411 switches are turned on with Logic 0 on the
appropriate control input, whereas the ADG1412 switches are
turned on with Logic 1. The ADG1413 has two switches with
digital control logic similar to that of the ADG1411; the logic is
inverted on the other two switches. Each switch conducts
equally well in both directions when on and has an input signal
range that extends to the supplies. In the off condition, signal
levels up to the supplies are blocked.
The ADG1413 exhibits break-before-make switching action for
use in multiplexer applications. Inherent in the design is low
charge injection, which results in minimum transients when the
digital inputs are switched.
