Hello everyone, I am new here, this is my first post, I hope you can help me, I am developing a project for my work, and I ran out with this IC, this is exactly what i need for the PCB i am designing, however the issue is I dont know if I have to put external components as capacitors, resistors or another IC to use this with an external sound signal to use it in a common output, please if someone have an idea about this, please share with me,

Thank in advance.

 

Just follow the data sheet.
Also add a 100nf ceramic decoupling capacitor between the V+ power pin and the ground pin.
