Temperature data format
Table 3
shows the relationship between the output digital data and the external temperature
for 12-bit resolution.
Temperature data for Temperature, T
OS
and T
HYS
Registers is represented by 9-bit, 10-bit,
11-bit, and 12-bit depending upon the resolution bits RC1, RC0 (Bits 6 and 5) in the
Configuration Register (see
Table 7 on page 17
). The default resolution is 9-bits.
The left-most hot in the output data stream controls temperature polarity information for
each conversion. If the Sign Bit is '0', the temperature is positive and of the Sign Bit is '1', the
temperature is negative.
