Dear all,
Please share you comments and experiences !

1) What happen I use DRV135 instead of the "Buffer OP" in BPA 200 ?
2) As above, I need to connect the "+" and "-" O/P from DRV134 to two grounps of LM3886. Which one you will think better, all of them use "invert" or "non-invert" ?

The first part of your question, I dont quite understand.

If you use inverted mode,you can adjust dc at output.

Use the DRV134 replace "U7" (LF411ACN)
