Overview
The ADG441BR-REEL, produced by Analog Devices Inc., is a monolithic CMOS device that comprises four independently selectable single-pole single-throw (SPST) switches. Designed on an enhanced LC2MOS process, this component offers low power dissipation, high switching speed, and low on-resistance. The ADG441 is particularly suited for applications requiring high linearity and low distortion, making it ideal for audio and video signal switching, as well as other precision applications.
