The least significant 19 bits of an external analog input's result register store sensor data in a floating-point format. The following equation describes an example of converting external analog input data formats.

Note: In the above example, only the 16 LSBs of the 19-bit format are listed. The bits 18:16 are not part of the mantissa and thus are fixed for a given format type.
