Overview
The ADG1234YCPZ-REEL7 is a monolithic iCMOS® analog switch produced by Analog Devices Inc. This device features four independently selectable single-pole, double-throw (SPDT) switches. It is designed using the iCMOS (industrial-CMOS) modular manufacturing process, which combines high voltage complementary metal-oxide semiconductor (CMOS) and bipolar technologies. This allows for high performance, low power consumption, and reduced package size, making it ideal for various applications including data acquisition, sample-and-hold, and video signal switching.
