TAS5086 Coefficient Parameter

Other Parts Discussed in Thread: TAS5086

Hello,

We have evaluate TAS5086 EVM and also download the TAS5086 PurePath(TM) GUI Version 4.0 for evaluation.

We can power on the EVM board and load the default CFG into the board to output sound.

But when we use TI Biquad coefficient filter generator to generate the parameters, we found that the output is not equal to the expected plotted result.

(Please refer to the attached 2 picture).

Please advise the correct tools (Biquad coefficient generator) for TAS5086.

Also, we also tried ALE 5.2 but it is not working too.

Thank you.

Hello Jones,

Thanks for sharing your concerns. I will look into this and get back to you. Can you tell me how you're measuring the BQ filter response for comparison with the GUI?
