... This application shows,however, some operative limits due to dissipation and current capability of the out- put stage. For this reason we recommend to use the TDA7269A in BTL with the following supply voltages depending on the used load impedance (for the single supply consider double Vs) : The detected characteristics of THD vs Pout are shown in figg and 9 for the different load impedances. ...
