GENERAL DESCRIPTION
The ADG1411/ADG1412/ADG1413 are monolithic
complementary 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 components 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 audio signals.

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 ADG1411/ADG1412/ADG1413 contain four independent
single-pole/single-throw (SPST) switches. The ADG1411 and
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, while Logic 1 is required for the
ADG1412. 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 for minimum transients when switching the
digital inputs.
