GENERAL DESCRIPTION
The ADG1211/ADG1212/ADG1213 are monolithic CMOS
devices containing four independently selectable switches
designed on an iCMOS process. iCMOS (industrial-CMOS) is a
modular manufacturing process combining high voltage CMOS
(complementary metal-oxide semiconductor) and bipolar
technologies. It enables the development of a wide range of high
performance analog ICs capable of 30 V operation in a footprint
that no previous generation of high voltage parts has been able
to achieve. Unlike analog ICs using conventional CMOS proc-
esses, iCMOS components can tolerate high supply voltages,
while providing increased performance, dramatically lower
power consumption, and reduced package size.
The ultralow capacitance and charge injection of these switches
make them ideal solutions for data acquisition and sample-and-
hold applications, where low glitch and fast settling are required.
Fast switching speed coupled with high signal bandwidth make
the parts suitable for video signal switching.

SWITCHES SHOWN FOR A LOGIC 1 INPUT
Figure 1.
iCMOS construction ensures ultralow power dissipation,
making the parts ideally suited for portable and battery-
powered instruments.
The ADG1211/ADG1212/ADG1213 contain four independent
single-pole/single-throw (SPST) switches. The ADG1211 and
ADG1212 differ only in that the digital control logic is inverted.
The ADG1211 switches are turned on with Logic 0 on the
appropriate control input, while Logic 1 is required for the
ADG1212. The ADG1213 has two switches with digital control
logic similar to that of the ADG1211; 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 ADG1213 exhibits break-before-make switching action for
use in multiplexer applications. Inherent in the design is low
charge injection for minimum transients when switching the
digital inputs.
