Hello.
I have need information about this chip.
I have seen the slaa447 document but it doesn't math exactly with this component.
Ideal would be to find, in addition to the formulas, examples with real numbers.
Thanks

Bruno,
Once you have your BiQuad coefficients for the frequency response of the filter. I have attached a spreadsheet that will help you convert the coefficient into the correct format needed to write to the registers. It includes a working example. Keep in mind TAS5721 uses 3.23 format and the B coefficients are the numerator and the A coefficients are the denominator. Sign inversion is need for the A coeffiecients.
Thank you for the spreadsheet.
Actually, in my float to 3.23 translation I have made an error (causing output distorsion).
Now translation is ok (with good result)
Regards
Bruno
