Abstract
A wireless device may include a plug that is shared by high speed data, analog audio signals, and power. Switches may be included on wires between the plug and the circuits that provide the high-speed data, analog audio signals and power to isolate those circuits from overvoltage conditions. Linearizer circuits may be included to provide gate driving signals to the switches, e.g., during transmission of analog audio signals. The linearizer circuits may include digital-to-analog converters to apply a gain factor to analog audio signals.
