    SLOU202 – June 2007 TAS5414 and TAS5424 Evaluation Module The TAS5414/TAS5424 evaluation module (EVM) is intended to be used to demonstrate the device's capabilities. All the device’s features can be accessed through the hardware and the software graphical user interface (GUI) supplied. This user's guide contains a description of the EVM and the GUI. Included are the EVM schematic, bill of materials, and the board layout.

  • Page 6: Initial Power Up

    This is the main window for the graphical user interface (GUI). The default state for the TAS5414 and TAS5424 is mute. To unmute, click the Play All button at the top left of the window. To mute, click the Mute All button.

  • Page 7: Description Of Outputs

    C is defeated(??). When the switch is moved to the Standby OFF position, the TAS5414 and TAS5424 are put into their default power-up mode. The I C registers are set to their defaults. The amplifier output is in Hi-Z mode.

  • Page 8: Clock Dither Circuit

    The EVM includes a clock dithering circuit for EMI mitigation. The dither circuit can be disconnected from the TAS5414 or TAS5424 device by removing the jumper JP1 on the PCB. The clock frequency changes ±5% in 50 ms. This was chosen to avoid interference with the audio signal. This circuit can aid in resolving potential AM interference issues.

  • Page 9: Using The Gui

    Channel 1-4: These four items provide individual channel output states. Hi-Z, Mute, Low-Low, and Play. The gain setting is displayed with the play indication. Fsw: This item provides the switching frequency of the outputs. SLOU202 – June 2007 TAS5414 and TAS5424 Evaluation Module Submit Documentation Feedback...
