3 Description

The TMP114 is a high accuracy, I2C-compatible

digital temperature sensor in an ultra-thin (0.15 mm)

4-pin package. The small size and low height of

the TMP114 package optimizes volume constrained

systems and enables novel placement of the sensor

under other surface mount components for the fastest

and most accurate temperature measurement.

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 100 tested on a production setup

that is NIST traceable.

To maximize battery life, 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.
