Description
-----------

The Texas Instruments TMP102 implements one temperature sensor.  Limits can be
set through the Overtemperature Shutdown register and Hysteresis register.  The
sensor is accurate to 0.5 degree over the range of -25 to +85 C, and to 1.0
degree from -40 to +125 C. Resolution of the sensor is 0.0625 degree.  The
operating temperature has a minimum of -55 C and a maximum of +150 C.

The TMP102 has a programmable update rate that can select between 8, 4, 1, and
0.25 Hz.

The TMP110 and TMP113 are software compatible with TMP102, but have different
accuracy (maximum error) specifications. The TMP110 has an accuracy (maximum error)
of 1.0 degree, TMP113 has an accuracy (maximum error) of 0.3 degree, while TMP102
has an accuracy (maximum error) of 2.0 degree.
