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.
