I’ve started working on the DSP module. Unfortunately, there is no KiCAD library for the ADA1442. Therefor I created the module by myself. You can download it here: ADAU1442 Kicad Library.
You don’t need an extra module, the TQFP-100 package is supplied withe the KiCAD standard libraries. However the ADAU1442 has a thermal pad on the bottom, that is missing at the KiCAD module.
