Low-Capacitance Hi-Speed USB for Both The devices feature a V detection input (V ) that can BUS B Channels (UNC and ANO) handle voltage up to 28V to automatically switch to the Distortion-Free Negative Signal Throughput USB signal path upon detection of a valid V signal (V Down to -1.8V on ANO Channel BUS B > V ). In a dead battery situation, the voltage on V 3I (typ) On-Resistance VBDET B can supply power to the part if V is greater than 4.5V. The 960MHz Bandwidth B MAX14585 features internal shunt resistors on the audio 0.04% THD+N Audio Channel path to reduce clicks and pops heard at the output. 15kV Human Body Model (HBM) ESD on COM1, COM2 The MAX14585/MAX14585A are available in a space- saving, 10-pin, 1.4mm x 1.8mm UTQFN package and S Saves Board Space Internal Shunt Resistor Reduces Clicks and operate over the -40NC to +85NC temperature range.
