Texas Instruments TMP114 Digital Temperature Sensor is a high accuracy, I2C-compatible digital temperature sensor in an ultra-thin (0.15mm) 4-pin package. The small size and low height of the TMP114 optimize volume-constrained systems and enables novel placement of the sensor under other surface mount components for fast and accurate temperature measurement.

The Texas Instruments TMP114 has an accuracy of ±0.3°C and offers an on-chip 16-bit analog-to-digital converter (ADC) that provides a temperature resolution of 0.0078°C. The TMP114 is 100% tested on a production setup that is NIST traceable. The TMP114 is designed to operate from a supply voltage range of 1.08V to 1.98 V, with a low average supply current of less than 0.7µA to maximize battery life.
