TMP117 High-Precision Digital Temperature Sensor Texas Instruments TMP117 High-Precision Digital Temperature Sensor is designed to meet ASTM E1112 and ISO 80601 requirements for electronic patient thermometers. The TMP117 provides a 16-bit temperature result with a resolution of 0.0078°C and an accuracy of up to ±0.1°C across the temperature range of -20°C to 50°C with no calibration. The TMP117 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-bit memory available for general use.
