Replacing Discrete Protection Components with Overvoltage Fault Protected Analog Switches

The challenge of designing robust electronic circuitry often results in a design with a multitude of discrete protection components with associated cost, design time and space additions. This article discusses the fault protected switch architecture, along with the performance benefits and other advantages it offers versus traditional discrete protection solutions. A new novel switch architecture and proprietary high voltage process which provides industry leading fault protection along with the performance required for precision signal chains is discussed. ADI’s new portfolio of fault protected switches and multiplexers (ADG52xxF and ADG54xxF) use this technology.
