Frequently Asked Questions
How accurate is the TMP114NBIYMTR temperature measurement and what resolution does it provide?
The TMP114NBIYMTR delivers ±1°C maximum accuracy with 16-bit digital resolution, corresponding to approximately 0.0078°C per LSB. This combination of high accuracy and fine resolution makes it suitable for precise thermal monitoring in medical wearables, laboratory instruments, and data center cooling management systems requiring better than 0.1°C temperature change detection.
How much current does the TMP114NBIYMTR draw during normal temperature conversion?
The TMP114NBIYMTR draws a maximum of 1.5 µA during active conversion, making it one of the lowest-power digital temperature sensors available. In shutdown mode the current drops further, extending battery life in coin-cell and energy-harvesting IoT designs that sample temperature once every few seconds rather than continuously.
Which interface does the TMP114NBIYMTR use for communication and how many devices can share a bus?
The TMP114NBIYMTR uses an I2C/SMBus 2-wire interface with configurable I2C address pins, allowing up to 4 devices on a single I2C bus without address conflicts. The 2-wire interface operates at standard 100 kHz and fast 400 kHz modes, making integration straightforward with microcontrollers that provide a hardware I2C peripheral on 3.3 V or 1.8 V supply systems.
What package does the TMP114NBIYMTR come in and how does this benefit miniaturized PCB designs?
The TMP114NBIYMTR is housed in a 0.76 mm × 0.76 mm BGA package with a height of only 0.132 mm, making it one of the smallest temperature sensors available for surface-mount assembly. This ultra-compact footprint is ideal for wearable patch sensors, hearing aids, and smartwatches where every fraction of a square millimeter of board area is valuable and conventional SOT or SOIC packages would be too large.
