This op-amp may want to be dc isolated from the input which currently
runs over dual 8V rails instead.  Similarly, the output might want to
be tailored to a 5V only (for example) control unit input.
This depth of 8 points around the commutator will yield a theoretical
maximum filter effect of 8x6=48dB, but extending this to 16 or more
bits is not out of the question

Good long term design takes care of these voltage shifts in one hit
but of course, this is just a bodged up test cct...
