GENERAL DESCRIPTION
The ADG1408 and ADG1409 are monolithic iCMOS analog
multiplexers 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 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
PRODUCT HIGHLIGHTS
1. 5 Ω max on resistance.
The iCMOS (industrial-CMOS) modular manufacturing
process combines high-voltage CMOS (complementary metal-
oxide semiconductor) and bipolar technologies. It enables the
development of a wide range of high performance analog ICs
capable of 30-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.
2. 0.5 Ω max on resistance flatness.
3. 3 V logic compatible digital input VIH = 2.0 V, VIL = 0.8 V.
4. 16-lead TSSOP and 4 mm ×4 mm LFCSP package.
