Texas Instruments Announces Ultra-Thin, 1.2-V to 1.8-V Supply, High Accuracy Digital Temperature Sensor with I2C Interface

Texas Instruments TMP114

Texas Instruments has announced the high-precision temperature sensor TMP114 with an I2C-compatible digital output in an ultra-thin (0.15 mm) 4-pin package. With a low height package, the TMP114 can be put under surface mount components for the fastest and most accurate temperature measurement and supports the latest thin form factor systems.

Texas Instruments - TMP114

The 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 designed to operate from a supply voltage range of 1.08 V to 1.98 V, with a low average supply current of less than 0.7 μA. The low supply support, along with extremely low power consumption, is designed for battery-powered applications. The TMP114 is 100% tested on a production setup that is NIST traceable.
