GENERAL DESCRIPTION
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.
The ADG1408-EP/ADG1409-EP are monolithic iCMOS® analog
multiplexers comprising eight single channels and four
differential channels, respectively. The ADG1408-EP switches
one of eight inputs to a common output, as determined by the
3-bit binary address lines, A0, A1, and A2. The ADG1409-EP
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.
Full details about this enhanced product are available in the
ADG1408/ADG1409 data sheet, which should be consulted in
conjunction with this data sheet.
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.
