Overview
The ADG412BRZ-REEL7, produced by Analog Devices Inc., is a monolithic CMOS device that comprises four independently selectable Single-Pole Single-Throw (SPST) switches. This component is part of the ADG412 series, which is designed on an enhanced LC2MOS process. This process ensures low power dissipation while providing high switching speed and low on-resistance. The ADG412 is particularly suited for applications requiring high signal integrity, such as audio and video switching, due to its flat on-resistance profile over the full analog input range and low distortion characteristics.
