Texas Instruments TMP117AIDRVR
The TMP117 is a high-precision digital temperature sensor. It is designedto meet ASTM E1112 and ISO 80601 requirements for electronic patient thermometers. The TMP117provides a 16-bit temperature result with a resolution of 0.0078°C and an accuracy of up to ±0.1°Cacross the temperature range of -20°C to 50°C with no calibration. The TMP117 has in interface thatis I2C- and SMBus™-compatible, programmable alert functionality, and thedevice can support up to four devices on a single bus. Integrated EEPROM is included for deviceprogramming with an additional 48-bits memory available for general use.
The low power consumption of the TMP117 minimizes the impact ofself-heating on measurement accuracy. The TMP117 operates from 1.8 V to 5.5 V and typicallyconsumes 3.5 µA.
For non-medical applications, the TMP117 can serve as a single chip digitalalternative to a Platinum RTD. The TMP117 has an accuracy comparable to a Class AA RTD, while onlyusing a fraction of the power of the power typically needed for a PT100 RTD. The TMP117 simplifiesthe design effort by removing many of the complexities of RTDs such as precision references,matched traces, complicated algorithms, and calibration.
The TMP117 units are 100% tested on a production setup that is NIST traceable andverified with equipment that is calibrated to ISO/IEC 17025 accredited standards.
