Texas Instruments TMP1826 Digital Temperature Sensor

Texas Instruments TMP1826 Digital Temperature Sensor is a 1-Wire® compatible sensor with an integrated 2kbit EEPROM and operates at -55°C to +150°C a wide operating temperature range. This temperature sensor provides a high accuracy of ±0.1°C (typical)/±0.3°C (maximum) across the temperature range of -20°C to 85°C.  The TMP1826 sensor features fast data rates of 90kbps in overdrive speed and flexible user-programmable short address modes for faster device addresses. This sensor also features four configurable open-drain digital input-output and temperature alerts. Applications include factory automation and control appliances, medical accessories, CPAP machines, battery packs, LED lighting, cold chain, temperature transmitters, and EV charging infrastructure.
