Key Features
- ±0.2 °C maximum accuracy over the full operating range eliminates external calibration in medical and industrial temperature measurement
- 16-bit resolution provides 0.0078 °C per LSB, enabling fine-grained temperature tracking in precision data-logging and HVAC applications
- Ultra-low 1.5 µA operating current extends battery life in coin-cell or energy-harvested IoT nodes and wearables
- 2-wire I2C interface with multiple programmable address pins allows up to 4 sensors on a single bus without additional logic
- 0.758 mm × 0.758 mm BGA package is among the smallest digital temperature sensors available, ideal for wearable and implantable designs
Applications
The TMP114CIYMTR is designed for wearable health monitors and body-temperature patches where ±0.2 °C accuracy and a sub-millimetre footprint are essential for clinical-grade readings without occupying meaningful skin area. It is also deployed in IoT edge nodes, smart building sensors, and battery-powered data loggers where the 1.5 µA quiescent current sustains years of operation from a 3 V coin cell. Industrial rack equipment and server thermal management use the 16-bit resolution for precise hot-spot detection and predictive fan-speed control.

Frequently Asked Questions
How accurate is the TMP114CIYMTR, and does that accuracy require user calibration?
The TMP114CIYMTR achieves ±0.2 °C maximum accuracy straight from the factory across its full operating temperature range, so no external calibration or trimming resistors are needed. This makes it suitable for medical-grade thermometry, food-safety monitoring, and clinical wearables where certification bodies require traceable accuracy within ±0.5 °C.
What resolution does the TMP114CIYMTR provide, and how does 16-bit output help in precision data-logging?
The device outputs a 16-bit digital word with a resolution of 0.0078 °C per LSB. In a data-logging application sampling at 1 Hz, this granularity lets firmware detect drift trends of less than 0.01 °C per hour—useful for monitoring battery pack thermal runaway early warning thresholds or tracking ambient temperature changes in a climate-controlled laboratory.
How much current does the TMP114CIYMTR draw, and how long can it run on a coin-cell battery?
Operating current is 1.5 µA maximum. A standard CR2032 coin cell with approximately 230 mAh capacity can theoretically power the TMP114CIYMTR for over 17 years of continuous sampling at 1 Hz, making it ideal for disposable medical patches, livestock ear-tag sensors, and building occupancy monitors where battery replacement is impractical.
Which communication interface does the TMP114CIYMTR use, and how many devices can share one bus?
The TMP114CIYMTR uses a 2-wire I2C interface running at standard (100 kHz) or fast (400 kHz) mode. Up to 4 devices with different address pin configurations can share a single I2C bus, allowing a microcontroller with one peripheral to read temperatures from multiple zones—for example 4 points across a PCB—without any additional multiplexer logic.
How small is the TMP114CIYMTR package, and what PCB layout rules apply?
The BGA body measures 0.758 mm × 0.758 mm with a height of only 0.132 mm, making it one of the smallest digital temperature sensors in production. Recommended PCB land pattern uses 0.3 mm diameter pads at 0.5 mm pitch; a no-clean flux and nitrogen-atmosphere reflow profile at 245 °C peak temperature ensures reliable solder joints at this ultra-fine pitch.
