GENERAL DESCRIPTION

The ADG1204 is a complementary metal-oxide semiconductor

(CMOS) analog multiplexer, comprising four single channels

designed on an iCMOS (industrial CMOS) process. iCMOS® is

a modular manufacturing process that combines 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 ultralow capacitance and charge injection of this multiplexer

makes it an ideal solution for data acquisition and sample-and-

hold applications, where low glitch and fast settling are required.

Fast switching speed coupled with high signal bandwidth makes

the part suitable for video signal switching. iCMOS construction

ensures ultralow power dissipation, making the part 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.
