Abstract

An apparatus relates generally to an analog switch. In such apparatus, the analog switch has a transistor. A first node of the transistor is coupled to an input node of the analog switch. A second node of the transistor is coupled to an output node of the analog switch. An overvoltage protection circuit is coupled to provide a control voltage to a gate node of the transistor. The overvoltage protection circuit is used to at least substantially reduce an overvoltage state caused by an analog voltage at the input node of the analog switch exceeding an overvoltage threshold voltage.
