GENERAL DESCRIPTION

The ADG1211/ADG1212/ADG1213 are monolithic CMOS devices containing four independently selectable switches designed on an iCMOS process. iCMOS (industrial-CMOS) is a modular manufacturing process combining high voltage CMOS (complementary metal-oxide semiconductor) and bipolar technologies. It enables the development of a wide range of high performance analog ICs capable of 30 V operation in a footprint that no previous generation of high voltage parts has been able to achieve. Unlike analog ICs using conventional CMOS proc­esses, iCMOS components can tolerate high supply voltages, while providing increased performance, dramatically lower power consumption, and reduced package size.
The ultralow capacitance and charge injection of these switches make them ideal solutions for data acquisition and sample-and­hold applications, where low glitch and fast settling are required. Fast switching speed coupled with high signal bandwidth make the parts suitable for video signal switching.

iCMOS construction ensures ultralow power dissipation, making the parts ideally suited for portable and battery­powered instruments.
The ADG1211/ADG1212/ADG1213 contain four independent single-pole/single-throw (SPST) switches. The ADG1211 and ADG1212 differ only in that the digital control logic is inverted. The ADG1211 switches are turned on with Logic 0 on the appropriate control input, while Logic 1 is required for the ADG1212. The ADG1213 has two switches with digital control logic similar to that of the ADG1211; the logic is inverted on the other two switches. Each switch conducts equally well in both directions when on, and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked.
The ADG1213 exhibits break-before-make switching action for use in multiplexer applications. Inherent in the design is low charge injection for minimum transients when switching the digital inputs.
