Applications
The TMP114NCIYMTR is designed for miniaturized wearable health monitors, medical body temperature patches, and IoT edge sensor nodes where board space and power budget are severely constrained. Its 16-bit resolution and ±1°C accuracy provide reliable thermal data for skin temperature measurement, hotspot detection in dense PCB assemblies, and battery thermal management. The wafer-level package with 0.758 mm footprint enables integration directly adjacent to heat-sensitive components in smartwatches and continuous glucose monitors.

Frequently Asked Questions
What is the temperature accuracy and resolution of the TMP114NCIYMTR, and how does this benefit medical wearable designs?
The TMP114NCIYMTR provides 16-bit resolution with ±1°C maximum accuracy across its operating range. For wearable skin temperature monitoring, 16-bit resolution enables detection of 0.0078°C increments, allowing firmware to track slow physiological temperature trends and fever onset with much finer granularity than 12-bit sensors with ±0.5°C typical accuracy.
For a coin-cell-powered IoT sensor node, how does the TMP114NCIYMTR's 1.5 µA current extend battery life?
At 1.5 µA maximum operating current and with one-shot measurement mode, a CR2032 coin cell of 225 mAh capacity could theoretically power the TMP114NCIYMTR for over 17 years of continuous measurement, or far longer with periodic sampling. This makes it practical for structural health monitoring tags and cold-chain loggers that must operate for years between battery changes.
How does the TMP114NCIYMTR's 0.758 mm x 0.758 mm package size compare to standard SOT-23 temperature sensors?
A standard SOT-23 package measures approximately 2.9 mm x 1.6 mm, occupying over 4.6 mm² of PCB area. The TMP114NCIYMTR's wafer-level package of 0.758 mm x 0.758 mm uses less than 0.6 mm², an 8x reduction in footprint. This enables placement in extremely tight spaces such as inside medical capsule devices, near IC hot spots on dense multi-chip modules, or in flexible PCB patches.
