I'm trying to make a small audio amplifier based on the TDA2030.
I was planning on building the circuit shown in the datasheet but then i found the one below which is more suitable as i only have 10w speakers
http://www.zen22142.zen.co.uk/Circuits/Audio/tda8.htm
I modelled up the circuit in multisim and sent a 1Khz sine wave into it but the output is a constant 1.4V
I can't see why it wouldn't work but then i'm still learning about this stuff, if i built this circuit would is work or not?
