The MediaTek MT8292 introduces the advantages of an input multiplexer, the headphone driver and the PGA outputs. The MT8292 performs 8:1 stereo input multiplexer. The analog input pins can  either independently support GPIO function or provide extra GPIO pins to use.

Each of the stereo PGA outputs as well as a headphone driver can reach 2Vrms in a 9V or 12V supply environment. On the other hand, through the two wire control, the MT8292 can control the digital function of the host IC (ie., the MT538x for example). Together with an external audio ADC and an audio DAC, the MT8292 can reach high voltage and gain output. […]
