 		 #181801 - subtracting 8.4V
Responding to: ???'s previous message
Per Westermark said:

If you start by subtracting 8.4V, you would have a signal between 0.1 and 0.6V that can then be scaled based on the range of the ADC. The scaling will also scale the DC error from the initial 8.4V subtraction.


8.4 V, For output swing of opamp?
