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.
