... UNC2 ANO1 ANO2 GND AOR Detailed Description The MAX14585/MAX14585A are high-ESD-protected single DPDT switches that operate from a 2.7V to 5.5V supply and are designed to multiplex Hi-Speed USB signals and AC-coupled analog signals. These switches combine the low on-capacitance (C tance (R ) necessary for high-performance switching ON applications ...

... V becomes the power supply Click-and-Pop Suppression (MAX14585) The switched 700I (typ) shunt resistors on the MAX14585 automatically discharge any capacitance at the ANO_ terminals when they are unconnected from COM_. This reduces audio click-and-pop sounds that can occur when switching between USB and audio sources. ...
