    Hi,
    I've just started making an amplifier for some speakers and I'm completely new to this and couldn't find any information in the documentation explaining it. So I just wanted to know if S-GND and PW-GND can be connected to a common ground back to the negative battery terminal? If not how would I go about connecting the grounds up?

    Datasheet: http://www.st.com/web/en/resource/technical/document/datasheet/CD00001048.pdf

    Thanks in advance :)
    Will


    *EDIT* I'm making the standalone version

    Quick answer is yes. If you look at the datasheet, their layout connects these signals together.
