could you tell me if this is correct.
Looking at the data sheet the mid sensitivity is about 8mv/G @ 5volts. If I use a 10bit adc @ 5volts then 5/1024=4.9 mV, so 1g=8mV so in bits 8/4.9=1.63 bits/g. Then if I have a zero adc reading of say 500 and I get a reading of 530, then
530-500- 30/1.63=18 g's.
Is that the way to calculate G's from this Breakout Board.
- the data sheet says that voltage as low as 3.5 could be used and I was thinking of trying both 3.7v and see if 3.3v will work. Any idea what this will do for the calculations and that maximum range. I know the sensitivity is ratiometric so that will drop based on a lower input voltage.
