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.
