GENERAL DESCRIPTION

The ADG1408/ADG1409 are monolithic iCMOS® analog multip-

lexers comprising eight single channels and four differential

channels, respectively. The ADG1408 switches one of eight

inputs to a common output, as determined by the 3-bit binary

address lines, A0, A1, and A2. The ADG1409 switches one of

four differential inputs to a common differential output, as

determined by the 2-bit binary address lines, A0 and A1. An EN

input on both devices is used to enable or disable the device.

When disabled, all channels are switched off.

The iCMOS (industrial CMOS) modular manufacturing process

combines high voltage CMOS (complementary metal-oxide

semiconductor) and bipolar technologies. It enables the devel-

opment of a wide range of high performance analog ICs capable

of 33 V operation in a footprint that no other 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 on resistance and on resistance flatness of these

switches make them ideal solutions for data acquisition and

gain switching applications where low distortion is critical.

iCMOS construction ensures ultralow power dissipation,

making the parts ideally suited for portable and battery-

powered instruments.
