7.3.7 Temperature Format

The temperature register data format of the TMP007 is reported in a binary twos complement signed integer

format, as Table 3 shows, with 1 LSB = (1 / 32)°C = 0.03125°C.

To convert the integer temperature result of the TMP007 to degrees Celsius, right-shift the result by two bits.

Then perform a divide-by-32 of TDIE and TOBJ, the 14-bit signed integers contained in the corresponding

registers. The sign of the temperature is the same as the sign of the integer read from the TMP007. In twos

complement notation, the MSB is the sign bit. If the MSB is 1, the integer is negative and the absolute value can

be obtained by inverting all bits and adding 1. An alternate method of calculating the absolute value of negative

integers is abs(i) = i xor FFFFh + 1.
