Overview
The ADG412BRU-REEL, produced by Analog Devices Inc., is a precision quad single-pole single-throw (SPST) analog switch. This monolithic CMOS device is designed on an enhanced LC2MOS process, which offers low power dissipation, high switching speed, and low on-resistance. The ADG412 is part of a family that includes the ADG411 and ADG413, differing primarily in their digital control logic. The ADG412 switches are turned on with a logic high on the appropriate control input, making it suitable for a variety of digital and analog applications.
