GENERAL DESCRIPTION

The ADG1201/ADG1202 are monolithic complementary

metal-oxide semiconductor (CMOS) devices containing

an SPST switch designed in an iCMOS® (industrial CMOS)

process. iCMOS is a modular manufacturing process

combining high voltage CMOS and bipolar technologies.

It enables the development of a wide range of high perform-

ance 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 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 construction ensures ultralow power dissipation,

making the parts ideally suited for portable and battery-

powered instruments.

The ADG1201/ADG1202 contain a single-pole/single-throw

(SPST) switch. Figure 1 shows that with a logic input of 1, the

switch of the ADG1201 is closed and that of the ADG1202 is

open. 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.
