Overview
The ADG412BRUZ-REEL, produced by Analog Devices Inc., is a monolithic CMOS device that comprises four independently selectable single-pole single-throw (SPST) switches. These switches are designed on an enhanced LC2MOS process, which ensures low power dissipation, high switching speed, and low on-resistance. This makes the ADG412 ideal for applications requiring high signal integrity and minimal power consumption.
The device is particularly suited for use in portable and battery-powered instruments due to its ultralow power dissipation. The ADG412 is also versatile, supporting both audio and video signal switching with excellent linearity and low distortion.
