Hi Jan, The datasheet for the TDA18218 can be obtained from NXP: http://www.nxp.com/documents/data_sheet/TDA18218HN.pdf That's all the information I have at the moment, maybe Mike has some other information (like the Application Note mentioned in the datasheet, that claims to contain information on writing drivers, but cannot be found anywhere).
