LA-55:
  DAC full range is 40A
  Actual bits is 16
  Stable bits is ~21

  CT full range is 55 A	    (FR + 0.5 bits)
  CT used range is 100 mA   (FR - 8.5 bits)
  ADC resolution over used range is about 8.5 bits
  Which would give us (FR - 17 bits)
  -- IF the LA-55 can measure 300uA.
     This would be 17.5 bits at its full range.
     Spec is around 1% = 7 bits.

CT-0.1:
  DAC full range is 60A
  Actual bits is 16
  Stable bits is ~21

  CT range is 5 mA (FR - 13 bits)
  ADC resolution over this range is about 8.5 bits
  Which would give us (FR - 21.5 bits)
  -- IF the CT-0.1 worked at all.. it's broken.
     It would be measuring 20uA.
     This would be 12.2 bits at its full range.
     Spec is around 1% = 7 bits.

A6302:
  DAC full range is 20A
  Actual bits is 16
  Stable bits is ~21

  CT range is 180mA   (FR - 6.8 bits)
  ADC resolution over this range is about 11 bits
  Which would give us (FR - 17.8 bits)
  -- Except CT resolution is only about 4 bits at this range.
     Which gives us 10.8 total, at best.
