PI3A6386 USB Type-C™ Ultra-Low THD Analog Audio Sw

Diodes' PI3A6386 includes a dual, single-pole-double-throw (SPDT) switch for high-speed USB signal and high-quality audio signal. The audio path with negative signal handling capability has a very low THD of -110 dB for high-quality audio requirements. It has a programmable soft-start/soft-stop feature to eliminate the click/pop sounds of DC-coupled audio signals. The data path has a high USB bandwidth of 1 GHz for USB high-speed (480 Mbps) signals. PI3A6386 can also detect the microphone signals in SBU1 and SBU2 and automatically route them to the correct inputs of the microphone amplifier.
