Overview
The ADG5434BCPZ-REEL7 is a high-voltage, latch-up proof, quad single-pole, double-throw (SPDT) analog switch produced by Analog Devices Inc. This monolithic industrial CMOS device is designed to provide robust and reliable switching solutions for various applications. The ADG5434 features four independently selectable SPDT switches, each exhibiting break-before-make switching action to prevent momentary shorting when switching channels. The device is available in a 20-lead LFCSP (4mm x 4mm with EP) package.
