Hello there,

SigmaStudio's 3.11.1 beta have this NLMS block for ADAU1452 but seems it is not functioning well. Pin0 and Pin1 are inverted, I believe, and there is no TC in in ADAU1452 as compared to the ADAU1761 chip. There's no documentation as far as I can search, so no clue as to how it works, except for some forum topics before related to this.

Using ADAU1452's NLMS block, I have tried BrettG's model design from here:https://ez.analog.com/message/26410#26410

but I got NO OUTPUT (pin0 &pin1 already inverted). ADAU1761's NLMS block works perfectly fine on this design model from BrettG.

Any thoughts as to what goes wrong on this NLMS ADAU1452 block?

Regards,

Dan

Hi Dan,

As far as we know this block works for the ADAU145x, it has been used in some of our demos.

Can you attach your project and we will take a closer look.
