The TMP118 is the industry smallest temperature sensor in an industry leading 0.55mm × 0.61mm × 0.24mm PICOSTAR package. The TMP118 provides a 16-bit temperature result with a resolution of 0.0078125°C and an accuracy of up to ±0.1°C across the temperature range of 0°C to 50°C with no additional calibration. The device is designed to help meet the system level ASTM E1112 and ISO 80601 accuracy requirements for electronic patient thermometers.

The TMP118 is designed to operate from a supply voltage as low as 1.4V, with a low average and shutdown current of 1.4µA (at 1Hz, no averaging) and 80nA, respectively, allowing for an on-demand temperature conversion to maximize battery life. The TMP118 has an interface that is I2C- and SMBus-compatible and has programmable alert functionality. Logic level as low as 1V can be supported regardless of the main supply rail, enabling interoperability with a low voltage 1.2V controller without an additional voltage level shifter.

The device offers unique IDs for improved traceability. The TMP118 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.
