I've seen the revised circuit. Does it work? I'm curious...
Resistors R5 and R6 on IC2A and R10 and R11 on IC2B will have two effects:
1) add a positive DC offset to the op-amps outputs
2) change the gain of the op-amp. In fact the original formula does not work anymore.
It is unusual to have an inverting amp (or a precision rectifier) using such a circuit...
I confirm that the original first post's schematic was correct.
If you need a DC offset, just refer to that schematic and omit R5 and R11 (use a short circuit in place of them). The offset can be obtained bay changing the value of R6 and R12.
I worked for a Company that sold thousands of audio mixers with circuits equivalent to the one in the first post. Don't know if I can find an old board to test, but if I can, I'll check the schematic.
Please refer to the original LM3915 application note
