Parallel Lm3886 Question

[woody]

When paralleling the LM3886 a small output resistor is used
on each chip. Would the LM3886 be stable if feedback was taken
after this output resistor instead of before it. If so couldn't we
parralle all the pins of the chip except the output pin. It sure would keep the parts count down.

The ICs would have to be absolutely identical for that. If that were the case, there would be no need for load sharing resistors in the first place. The current state of production technology does not allow for such accuracy, so no, it would not work.

Do a search for op amp stacking.
