I've tried to do a layout for TDA2030 amp, and would like to share and ask you guys to have a look and see if they can find any errors.
Also I'd like to know if there's a mod to get -9v/+9v from the bipolar daughter board that Mark posted few days ago.
Also bear in mind that I don't think the pins of the TDA2030 have a 2.5mm pitch between consecutive pins like vero requires, so I think you'll have to spread the pins out a bit to get them in the required holes. Not a biggie but something to bear in mind.
I've built it, figured there is an error in the schematics I provided and pins 4 and 5 on the TDA2030 should be swapped.
The problem is, the damn thing doesn't work yet... Double checked the schematics, the layout, cuts, part numbers... Any ideas, guys?
Thinking about building this - your layout looks good to me too. One question for you - you haven't grounded the tab on the IC by heatsinking it, have you? According to the datasheet, it's connected to Pin 3 which is V-
Also. . . yes, you're right, the schematic from ggg is wrong, has pins 4 and 5 mis-labeled. But their PCB layout is right. So this layout either needs to have the IC pin connections swapped, or have those two rows switched around. Still haven't built one - thinking I might just make a PCB instead of doing this on vero. Bending those little legs on the IC makes me nervous. I've broken them from handling them too much before, they're not very robust where they go into the body of the IC.
