The sensitivity for this accelerometer is listed as 1mg/digit at +/-2g FS. This brings up a few questions. First, is a "digit" and LSB?? Second, at 16 bits, a LSB would be about 0.06 mg, not 1.0 mg. There's something I'm not understanding. What's the resolution of the ADC, and what's the ENOB of this accelerometer?
