Overview
The ADG783BCPZ is a monolithic CMOS device produced by Analog Devices Inc., featuring four independently selectable single-pole/single-throw (SPST) switches. This component is designed on an advanced submicron process, ensuring low power dissipation, high switching speed, and low on-resistance. It operates from a single supply voltage ranging from 1.8 V to 5.5 V, making it suitable for battery-powered instruments and modern DACs and ADCs. The ADG783BCPZ is available in a 20-lead chip scale package (LFCSP) with a compact 4mm x 4mm footprint.
