What are the key features of TMP114CIYMTR?
- ±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
What is TMP114CIYMTR used for?
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.
