The MAX14585/MAX14585A high-ESD-protected double-pole/double-throw (DPDT) switches multiplex Hi-Speed (480Mbps) USB and analog signals such as AC-coupled audio or video. These devices combine the low on-capacitance (CON) and low on-resistance (RON) necessary for high-performance switching applications in portable electronics and include an internal negative supply to pass audio signals that swing below ground down to -1.8V. The devices also handle USB low-/full-speed signaling and operate from a 2.7V to 5.5V supply.The devices feature a VBUSdetection input (VB) that can handle voltage up to 28V to automatically switch to the USB signal path upon detection of a valid VBUSsignal (VB> VVBDET). In a dead battery situation, the voltage on VBcan supply power to the part if VBis greater than 4.5V. The MAX14585 features internal shunt resistors on the audio path to reduce clicks and pops heard at the output.The MAX14585/MAX14585A are available in a space-saving, 10-pin, 1.4mm x 1.8mm UTQFN package and operate over the -40°C to +85°C temperature range.ApplicationsCell PhonesPDAs and Handheld DevicesTablet PCs
