TI TMP117MAIDRVR

The TMP117 is a high-precision digital temperature sensor designed to meet ASTM E1112 and ISO 80601 requirements for medical electronic thermometers. It provides 16-bit temperature results with 0.0078℃ resolution, achieving up to ±0.1℃ accuracy over the -20℃ to 50℃ temperature range without calibration. The TMP117 features an I²C- and SMBus™-compatible interface with programmable alert functionality, supports up to four devices on a single bus, includes integrated EEPROM for device programming and an additional 48-bit memory for general-purpose use. Its low power consumption minimizes the effect of self-heating on measurement accuracy. The TMP117 operates over a 1.7 V to 5.5 V supply range with a typical current of 3.5 μA. TMP117 devices are 100% tested during production, NIST-traceable, and verified using equipment calibrated to ISO/IEC 17025-accredited standards. For all available packages, refer to the Package Options appendix at the end of the datasheet.
