2.3.1 TAx5x42 EVM Input Hardware Settings

The TAx5x42 evaluation module has several input configuration options and offers extensive flexibility to allow the user to evaluate the device across multiple operation modes. The different operation modes are highlighted in this section.

GUID-20230611-SS0I-JPFG-TTXT-S0GMDRWWJ8XN-low.pngFigure 2-8 TAC5242/TAC5142/TAA5242 EVM Input Architecture for Channel 1 and 2

The IN1 and IN2 input architecture allows these two channels to be quickly configured to support any of the supported operation modes. The INxP and INxM pins of the TAx5x42 can optionally connect to onboard microphones for quick evaluation of a microphone in AC- or DC-coupled modes. Jumper configuration details can be found in Table 3-2.

For TAD5242 or TAD5142, IN1 and IN2 components are not populated.
