8.2.1 Application

Figure 8-1 shows a typical configuration of the TAC5312-Q1 for an application using two analog ECM microphones for simultaneous recording and two channel lineout operation with an I2C control interface and a time-division multiplexing (TDM) audio data target interface. For best distortion performance, use input AC-coupling capacitors with a low-voltage coefficient.
