Digital Microphone Function
In addition to supporting analog microphones, the TLV320AIC3111 can also interface to one digital
microphone using using the mono ADC channel. Figure 5-17 shows the digial microphone interface block
diagram and Figure 5-18 shows the timing diagram for the digital microphone interface.
