نظرة عامة على المنتج
The TMP117MAIDRVR from Texas Instruments is a high-accuracy digital temperature sensor with I2C/SMBus interface, achieving ±0.1°C accuracy from -20°C to +50°C without calibration. With 16-bit resolution (0.0078°C/LSB), 3.5µA operating current, and NIST traceability, it is a PT100/PT1000 RTD replacement in a tiny WSON-6 package.
