Electronic – SENT protocol output unit is LSB. What does this mean

protocolsensorsymbol [~]transistorsunits

I have read couple of datasheet of devices which uses SENT protocol. They define the output between 193 and 3896. The unit is LSB. I think that this does not mean least significant bit?

Example:

It does in fact mean LSB or, alternatively, the measurement amount corresponding to 1 LSB. The specs you're looking at are measurement ranges. The numbers given are the highest and lowest readings you can expect. Note that they're 12-bit readings, meaning they have a potential (positive) range of 0 to 4095. 4095 what? Depends how it's calibrated, but to skirt that quagmire, they call it a LSB and spec those ranges accordingly. It's kind of like using "percent of full scale" as a unit, but the fact that it's already digitized makes LSB a natural unit.
