temperature. Temperature data for the Temperature, T
represented as a 9-bit, two’s complement word.
The left-most bit in the output data stream contains temperature polarity information for each
conversion. If the sign bit is '0', the temperature is positive and if the sign bit is '1,' the
temperature is negative.
Table 3.
