I thought I might try the output stage for the CS4397 posted here. So, I thought I would put my new Eagle skills to work and do a board.
I have recreated the schematic here:
And, here is my layout:
The board is 40mm x 60mm and will require two for the complete output stage.
I have assumed BC550C for Q1, Q3, Q4 & Q6 & a BC517 for Q2, and used the Murata 2200R inductors from Digikey.
You might note that for the output cap I have provided the option to use either a large(ish) film cap (c2) or an electrolytic bypassed by a smaller film cap (C9 & C10). Is this a sensible option and implementation?
This is my first board layout, so all comments welcome.
Cheers
