TLV320ADC5120: the difference between microphone input and line input of 0x3C reg

Hey Shubiao,

The difference between a line input and the mic input is the voltage levels. Typically the line input voltage is about 1V and higher than mic input voltage which could be in mV. Hope this answers your question.
