TAS5780M: TAS5780M: How to set I2S format and stereo output in I2C register table

Victor Tam

Part Number: TAS5780M

Dear Expert,

I got the Pure Path Console 3 tool to tune TAS5780M amplifier. We have problem on how to config I2S format and stereo output in I2C register table.

Which book/page/register to config I2S format?

What I2C register actually needed to write into TAS5780M to get the results? There are so many registers including EQ setting.

Below is the example of our schematics. Thanks in advance for helping.

Best Regards,

Victor Tam

Hi Victor,

What's the format of your audio input? TAS5780M supports I2S with its default settings.

See the screenshot below. It should be the register you were looking for.

Hi Andy,

Thanks. It's working now.

It seems the data extracted by the PP3 tool did not include those param data in Page 0.

After adding those data for I2C initialization, it was working.

And also need to config the param as you stated and the DAC, CLK, etc in Page 0.

Thanks for your support.

Best Regards,

Victor
