GENERAL DESCRIPTION

The ADG1404 is a complementary metal-oxide semiconductor

(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 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.

iCMOS construction ensures ultralow power dissipation,

making the parts ideally suited for portable and battery-

powered instruments.

The ADG1404 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.
