Figure 2-4. 5.23 Format
The decimal value of a 5.23 format number can be found by following the weighting shown in Figure 2-5. If
the most significant bit is logic 0, the number is a positive number, and the weighting shown yields the
correct number. If the most significant bit is a logic 1, then the number is a negative number. In this case,
every bit must be inverted, a 1 added to the result, and then the weighting shown in Figure 2-5 applied to
obtain the magnitude of the negative number.
Figure 2-5. Conversion Weighting Factors—5.23 Format to Floating Point
Gain coefficients, entered via the I2C bus, must be entered as 32-bit binary numbers. The format of the
32-bit number (4-byte or 8-digit hexadecimal number) is shown in Figure 2-6.

As Figure 2-6 shows, the hexadecimal (hex) value of the integer part of the gain coefficient cannot be
