The ADG1211/ADG1212/ADG1213 are monolithic complemen- The ADG1211/ADG1212/ADG1213 contain four independent tary metal-oxide semiconductor (CMOS) devices containing single-pole/single-throw (SPST) switches. The ADG1211 and four independently selectable switches designed on an iCMOS® ADG1212 differ only in that the digital control logic is inverted. (industrial CMOS) process. iCMOS is a modular manufacturing The ADG1211 switches are turned on with Logic 0 on the process combining high voltage CMOS and bipolar technologies. appropriate control input, while Logic 1 is required for the It enables the development of a wide range of high performance ADG1212. The ADG1213 has two switches with digital control analog ICs capable of 33 V operation in a footprint that no previous logic similar to that of the ADG1211; the logic is inverted on the generation of high voltage devices has been able to achieve. other two switches. The ADG1213 exhibits break-before-make Unlike analog ICs using conventional CMOS processes, iCMOS switching action for use in multiplexer applications. components can tolerate high supply voltages while providing Each switch conducts equally wel in both directions when on increased performance, dramatically lower power consumption, and has an input signal range that extends to the supplies. In the and reduced package size. off condition, signal levels up to the supplies are blocked. The ultralow capacitance and charge injection of these switches
