The TI SMBus / i2C TMP116/TMP116N Digital Temp. Sensor

This is the TMP116 a high accuracy, low power digital temperature sensor with SMBus and i2c interface from Texas Instruments. This device runs on low power in a high precision temperature sensor with integrated memory. The TMP116 features a 16bit temperature result with a resolution of 0.0078 degree Celsius and an accuracy of up to -0.2 / +0.2 degree Celsius with no calibration. This device runs on i2C and SMBus-interface, it has programmable alert functionality and can support up to four devices on a single bus.

The TMP116 consumes minimal current that can provide a power saving option minimize self-heating and improves measurement accuracy. The TMP116 operates from 1.9v to 5.5v and typically consumes 3.5 uA. Across the device operating temperature range of -55 degree Celsius to 125 degree Celsius the TMP116 exceeds the accuracy of a class A RTD while consuming less than 1-5th of the typical excitation current for a PT100 RTD.

The TMP116 is easier to use than RTDs calibration is not required, external circuitry, matched traces and kelvin connections. This device is suitable for used in environmental monitoring/ thermostats, Environmental Air Temperature Monitoring, wearable devices, asset tracking/cold chain, gas meters and heat meters, test measurement, and cold junction compensation of thermocouple.
