Overview
The ADG1211YRUZ is a monolithic complementary metal-oxide semiconductor (CMOS) device produced by Analog Devices Inc. It features four independently selectable single-pole/single-throw (SPST) switches designed on the iCMOS (industrial CMOS) process. This process combines high voltage CMOS and bipolar technologies, enabling the development of high-performance analog ICs capable of 33 V operation in a compact footprint. The ADG1211YRUZ is part of the ADG1211/ADG1212/ADG1213 series, differing primarily in their digital control logic. The ADG1211 switches are activated with Logic 0, while the ADG1212 requires Logic 1, and the ADG1213 has a mix of both logic types and exhibits break-before-make switching action for multiplexer applications.
