349 This op-amp may want to be dc isolated from the input which currently
350 runs over dual 8V rails instead. Similarly, the output might want to
351 be tailored to a 5V only (for example) control unit input.
352 This depth of 8 points around the commutator will yield a theoretical
353 maximum filter effect of 8x6=48dB, but extending this to 16 or more
354 bits is not out of the question
356 Good long term design takes care of these voltage shifts in one hit
357 but of course, this is just a bodged up test cct...
