| 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. | |
