1.4 Device Information

The TMP119 is a high-precision digital temperature sensor. 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. TMP119 is NIST traceable. TMP119 is designed to meet ASTM E1112 and ISO 80601 requirements for electronic patient thermometers. For non-medical applications, the TMP119 can serve as a single chip digital alternative to a Platinum RTD. For more information of the IC, please refer to the device data sheet. Table 2-3 includes some of the parameters of interest of the TMP119 to consider when using this EVM.
