TMP116/TMP116N Digital Temperature Sensors

Texas Instruments TMP116/TMP116N Digital Temperature Sensors are low-power, high-precision temperature sensors with integrated EEPROM memory. The TMP116 provides a 16-bit temperature result with a resolution of 0.0078°C and an accuracy of up to ±0.2°C with no calibration. The device is I2C and SMBus interface compatible, has programmable alert functionality, and can support up to four devices on a single bus. The TMP116 consumes minimal current that, in addition to providing power savings, minimises self-heating and improves measurement accuracy. The TMP116 operates from 1.9V to 5.5V and typically consumes 3.5µA. Across the device operating temperature range of –55°C to +125°C, the TMP116 exceeds the accuracy of a Class A RTD, while consuming less than one fifth of the typical excitation current for a PT100 RTD. The TMP116 is easier to use than RTDs, eliminating the need for calibration, external circuitry, matched traces, and Kelvin connections.
