The ADG1433YRUZ-REEL7 and ADG1434 are monolithic industrial CMOS(iCMOS®) analog switches comprising three independentlyselectable single-pole, double-throw (SPDT) switches andfour independently selectable SPDT switches, respectively.
All channels exhibit break-before-make switching action thatprevents momentary shorting when switching channels. An ENinput on the ADG1433YRUZ-REEL7 (LFCSP and TSSOP) and ADG1434(LFCSP only) is used to enable or disable the device. Whendisabled, all channels are switched off.
The iCMOS modular manufacturing process combines highvoltage, complementary metal-oxide semiconductor (CMOS),and bipolar technologies. It enables the development of a widerange of high performance analog ICs capable of 33 V operationin a footprint that no other generation of high voltage deviceshas been able to achieve. Unlike analog ICs using a conventionalCMOS process, iCMOS components can tolerate high supplyvoltages while providing increased performance, dramaticallylower power consumption, and reduced package size.
The ultralow on resistance and on resistance flatness of theseswitches make them ideal solutions for data acquisition and gainswitching applications, where low distortion is critical. iCMOSconstruction ensures ultralow power dissipation, making thedevices ideally suited for portable and battery-poweredinstruments.
