The ADG1208YRZ-REEL7 and ADG1209 are monolithic, iCMOS® analogmultiplexers comprising eight single channels and four differentialchannels, respectively. The ADG1208YRZ-REEL7 switches one of eight inputsto a common output as determined by the 3-bit binary addresslines A0, A1, and A2. The ADG1209 switches one of fourdifferential inputs to a common differential output as determinedby the 2-bit binary address lines A0 and A1. An EN input onboth devices enable or disable the device. When disabled, allchannels are switched off. When on, each channel conductsequally well in both directions and has an input signal rangethat extends to the supplies.
The iCMOS (industrial CMOS) modular manufacturingprocess combines high voltage CMOS (complementary metal-oxidesemiconductor) and bipolar technologies. It enables thedevelopment of a wide range of high performance analog ICscapable of 33 V operation in a footprint that no other generationof high voltage devices has been able to achieve. Unlike analogICs using conventional CMOS processes, iCMOS componentscan tolerate high supply voltages while providing increasedperformance, dramatically lower power consumption, andreduced package size.
The ultralow capacitance and exceptionally low charge injectionof these multiplexers make them ideal solutions for data acquisitionand sample-and-hold applications, where low glitch and fastsettling are required. There is minimum chargeinjection over the entire signal range of the device. iCMOSconstruction also ensures ultralow power dissipation, making theds ideally suited for portable and battery-powered instruments.
