Category: Switches and Multiplexers

The ADG1233 and ADG1234 are monolithic iCMOS® analogswitches comprising three independently selectable single-pole,double throw SPDT switches and four independently selectableSPDT switches, respectively.All channels exhibit break-before-make switching actionpreventing momentary shorting when switching channels. AnEN input on the ADG1233 and ADG1234 enables or disablesthe device. When disabled, all channels are switched off.The iCMOS (industrial-CMOS) modular manufacturing processcombines a high voltage complementary metal-oxide semiconductor(CMOS) 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 generation ofhigh voltage devices has been able to achieve.Unlike analog ICs using conventional CMOS processes, iCMOScomponents can tolerate high supply voltages while providingincreased performance, dramatically lowered power consumption,and reduced package size.The ultralow capacitance and charge injection of these multiplexersmake them ideal solutions for data acquisition and sample-andholdapplications, where low glitch and fast settling are required.Fast switching speed coupled with high signal bandwidth make thedevices suitable for video signal switching. iCMOS constructionensures ultralow power dissipation, making the devices ideallysuited for portable and battery-powered instruments.Product Highlights 1.5 pF off capacitance (±15 V supply). 0.5 pC charge injection. 3 V logic-compatible digital input, VIH = 2.0 V, VIL = 0.8 V. 16-lead TSSOP, 20-lead TSSOP, and 4 mm × 4 mm LFCSP.Applications Audio and video routing Automatic test equipment Data acquisition systems Battery-powered systems Sample-and-hold systems Communication systems
