What is the difference between LSB/g , Count/g and mV/g?

I know that all this are used to measure sensitivity in accelerometers. It's easy to understand the concept of mV/g but I didn't find any useful information about LSB/g and Count/g. Is there any relation between them?

Thank you all in advance!

Solution

  • The accelerometer has an analog output in mV. That's converted by an A to D, resulting in a number of some range. (E.g., a 12-bit A to D would give a number between 0 and 4095.) LSB/g and count/g would give the sensitivity of this output number.
