GENERAL DESCRIPTION
The ADG1233 and ADG1234 are monolithic iCMOS® analog Unlike analog ICs using conventional CMOS processes, iCMOS switches comprising three independently selectable single-pole, components can tolerate high supply voltages while providing double throw SPDT switches and four independently selectable increased performance, dramatically lowered power consumption, SPDT switches, respectively. and reduced package size. All channels exhibit break-before-make switching action The ultralow capacitance and charge injection of these multiplexers preventing momentary shorting when switching channels. An make them ideal solutions for data acquisition and sample-and- EN input on the ADG1233 and ADG1234 enables or disables hold applications, where low glitch and fast settling are required. the device. When disabled, all channels are switched off. Fast switching speed coupled with high signal bandwidth make the The iCMOS (industrial-CMOS) modular manufacturing process devices suitable for video signal switching. iCMOS construction combines a high voltage complementary metal-oxide semi- ensures ultralow power dissipation, making the devices ideally conductor (CMOS) and bipolar technologies. It enables the suited for portable and battery-powered instruments. development of a wide range of high performance analog ICs
