Overview
The ADG512BRZ from Analog Devices Inc. is a monolithic CMOS IC that contains four independently selectable analog switches. These switches are part of the ADG511, ADG512, and ADG513 series, which are fabricated using Analog Devices’ advanced linear compatible CMOS (LC2MOS) process. This process ensures low leakage currents, ultralow power dissipation, and low capacitance, enabling fast switching speeds with minimal charge injection. The ADG512 is particularly suited for precision analog signal switching tasks in various applications, including battery-operated instruments, single supply systems, and data acquisition systems.
