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.
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.
Internal Diagram
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.
