Overview
The ADG1434YCPZ-REEL7, produced by Analog Devices Inc., is a monolithic industrial CMOS (iCMOS®) analog switch. This device is part of the ADG1434 series, which comprises four independently selectable single-pole, double-throw (SPDT) switches. The ADG1434 is designed to offer high performance and reliability in various industrial and commercial applications.
The device features rail-to-rail operation and break-before-make switching action, which prevents momentary shorting when switching channels. It also includes an enable input (EN) for the LFCSP package, allowing the device to be enabled or disabled as needed.
