8.2.1 Application

Figure 8-1 shows a typical configuration of the TAC5242 for an application using a 2-channel differential AC-coupled microphone operation and a 2-channel differential line-out operation with a Target Mode I2S audio serial data interface. For best distortion performance, use input AC-coupling capacitors with a low-voltage coefficient.
