Hi, new guy here. Long time reader, first time posting
I'm working on my first PCB ever, it's going to be an audio amplifier. I'm using Eagle and made my own part.
Problem is that the auto placed tStop layer is bigger than the SMD pad. So in the board view there is no soldermask between the pads.
Is there a way to modify this or will my board house (seeed) auto fix it?
Second problem is that the chip (MAXIM MAX9744) requires 3-3.6v on Vdd? Seems quite odd to me. Never saw an amplifier that converted the main (PVDD) voltage to a lower voltage. What is it used for, can I skip it?
Thanks in advance
. I will probably post some more questions along the way if I can't find them myself.
