Overview
The ADG411BRU, produced by Analog Devices Inc., is a monolithic CMOS device that comprises four independently selectable SPST (Single-Pole Single-Throw) switches. These switches are designed on an enhanced LC2MOS process, which offers low power dissipation, high switching speed, and low on-resistance. This makes the ADG411BRU ideal for applications requiring high signal integrity and low power consumption, such as in portable and battery-powered instruments.
