The TMP119 is a high-precision digital temperature sensor. The device is designed to help meet ASTM E1112 and ISO 80601 accuracy requirements for electronic patient thermometers. The TMP119 provides a 16-bit temperature result with a resolution of 0.0078°C and an accuracy of up to ±0.08°C across the temperature range of 0°C to 45°C with no calibration. The TMP119 has an interface that is I2C- and SMBus™-compatible, programmable alert functionality, and the device can support up to four devices on a single bus. Integrated EEPROM is included for device programming with an additional 48-bits memory available for general use. The TMP119 operates from 1.7V to 5.5V and typically consumes 3.5µA for a 1Hz conversion cycle.
For non-medical applications, the TMP119 can serve as a single chip digital alternative to a Platinum RTD. The TMP119 has an accuracy comparable to a Class AA RTD, while only using a fraction of the power of the power typically needed for a PT100 RTD. The TMP119 simplifies the design effort by removing many of the complexities of RTDs such as precision references, matched traces, complicated algorithms, and calibration. The device is designed to be strain tolerant, allowing robustness over typical strains often seen in PCB manufacturing, including device soldering, molding, underfill, and board flexing.
The TMP119 units are 100% tested on a production setup that is NIST traceable and verified with equipment that is calibrated to ISO/IEC 17025 accredited standards.
