±0.2°C Accurate Digital Temperature Sensor With NV Memory

 

Description

The TMP116 family (TMP116, TMP116N) consist of 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 TMP116 is compatible with the I2C- and SMBus interface, has programmable alert functionality, and supports up to four devices on a single bus.

The TMP116 consumes minimal current that, in addition to providing power savings, minimizes self-heating and improves measurement accuracy. The TMP116 operates from 1.9 V to 5.5 V and typically consumes 3.5 µA.

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.

The TMP116 units are 100% tested on a production setup that is NIST traceable and verified with equipment that is calibrated to ISO/IEC 17025 accredited standards.
