Overview
The ADG411BR is a precision quad single-pole single-throw (SPST) analog switch produced by Analog Devices Inc. This monolithic CMOS device is designed on an enhanced LC2MOS process, which ensures low power dissipation, high switching speed, and low on-resistance. The ADG411BR is part of the ADG411, ADG412, and ADG413 family, differing primarily in the digital control logic. The ADG411BR switches are turned on with a logic low on the appropriate control input.
The device is well-suited for applications requiring high linearity and low distortion, particularly in audio and video signal switching. Its ultralow power dissipation makes it ideal for portable and battery-powered instruments.
