Overview
The ADG412BR, produced by Analog Devices Inc., is a versatile and highly efficient monolithic CMOS device. It features four independently selectable SPST (Single-Pole Single-Throw) switches, making it ideal for various applications requiring flexible routing and switching. Developed using an enhanced LC2MOS process, this device excels in providing low power dissipation, high-speed switching, and minimal on resistance. Each switch conducts equally well in both directions and has an input signal range that extends to the supply rails. The ADG412BR is particularly suited for applications where low power consumption and fast switching times are critical.
