TAS5711 EVM Questions

Other Parts Discussed in Thread: TAS5711, TAS5713

Could you please take a look at the following questions about the TAS5711EVM and help me answer them for the customer:

 

I've been digging into the TAS5711EVM kit to see if it can be used to help us do a quick evaluation of the loudness of the speakers we are proposing to use in the Hurricane demo. I have a few questions, but I'm not sure which of you to ask, so I've copied everyone.

 

1)      Is there a newer version of the TAS5711EVM users guide than the one on the TI web site I've downloaded the GUI software and noticed that there a number of inconsistencies in the users guide relative to what the GUI presents?

 

2)      Is there a configuration file that sets up the EVM kit to simply put the EVM in 2.1 mode and pass signals from the LIN/RIN (analog) connectors to the speakers with or without any equalization etc.?

 

3) What is the difference between the TAS5711 and TAS5713? From a quick look at the datasheets, it appears that the TAS5713 is intended for driving lower impedance loads, but has a recommended PVDD of 21.5 rather than 26V.

 

Thank you very much for your help!

    Hi, Joe,

    You are correct, looks like the User's Guide refers to the old GUI version, but the TAS5711 is controlled with the TAS57x1 GUI. You may use the TAS5731EVM User's guide as a reference, these devices uses the same GUI.

    In order to use analog inputs to drive the amplifier, some adjustments in MC57xx are required:

    • Select ADC in JP4 and JP5 (short on pins 1 and 2).
    • Audio CLK jumpers (JP6-JP10) should be connected with pins 1 and 2 tied. 

    JP2 and JP3 will limit the input voltage:

    • IN: LIN/RIN = 1Vrms MAX.
    • OUT: LIN/RIN = 2Vrms MAX. 

    No changes are required on the amplifier as I2S signals comes from the motherboard.

    TAS5711 and TAS5713 have different audio processing features, and yes, the TAS5713 is able to drive 4Ohm in BTL.
