GENERAL DESCRIPTION

The ADG1204 is a CMOS analog multiplexer, comprising four

single channels designed on an iCMOS process. iCMOS

(industrial-CMOS) is a modular manufacturing process that

combines 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 other genera-

tion 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 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. iCMOS construc-

tion ensures ultralow power dissipation, making the parts

ideally suited for portable and battery powered instruments.

The ADG1204 switches one of four inputs to a common output,

D, as determined by the 3-bit binary address lines, A0, A1, and

EN. Logic 0 on the EN pin disables the device. Each switch

conducts equally well in both directions when on, and has an

input signal range that extends to the supplies. In the off condi-

tion, signal levels up to the supplies are blocked. All switches

exhibit break-before-make switching action. Inherent in the

design is low charge injection for minimum transients when

switching the digital inputs.
