Why do you want to simulate a low power audio amplifier? The datasheet shows you everything you would need to make a little audio amp with it.
Oh, is this school work?
Maybe your teacher does not want to teach anything but instead wants you to find a model for the old TDA7052 amplifier yourself, if a model was ever made for it.
Maybe your teacher wants you to learn how to take information from the datasheet and make the model yourself, instead of teaching you how to do it.
Maybe your teacher does not know how to find a model and does not know how to make a model.
