How to add IC tda 2003 to the library in Proteus?

Hi everyone, I'm Brazilian and this is my first post here. I'm graduating in Mechanical Engineering. In Brazil, in order to conclude our graduation, we have to build a project. I'm working in ANC (Active Noise Control) for ducts. The Professor that orientates me, asked to build a sound amplifier so as to amplify the signal that leaves my Arduino. I based on this video (link ) and it perfectly worked. I used a signal generator and an oscilloscope to confirm that. However, my Professor also said I had to simulate the circuit because it's an academic work. The problem is that I'm using Proteus and I couldn't find the IC tda 2003 in the library. As a Mechanical Engineer, I don't know much about this softwares, but I need to simulate this circuit. Is there any way to download a library wich has this component? Or I have to do this simulation in another software? Thanks all of you and I'm sorry if there was some grammar mistakes.
