Product details
Overview
TMP114DIYMTR from Texas Instruments is a high-accuracy, ultra-thin digital temperature sensor with I²C/SMBus interface, ±0.2°C max error from 20°C to 50°C, 16-bit resolution (0.0078°C LSB), and 0.7 µA average supply current - deployed in mobile phones, SSDs, and wearable fitness monitors for real-time thermal management.
For engineers reviewing the TMP114DIYMTR datasheet, TMP114DIYMTR pinout, TMP114DIYMTR application, or TMP114DIYMTR equivalent, this page delivers verified technical context, NIST-traceable accuracy specs, I²C timing compliance, ultra-low-power operating conditions, and validated alternative options for thermal sensing in space-constrained, battery-powered systems.
Technical Context
The TMP114DIYMTR integrates a factory-calibrated bandgap-based thermal sensor, 16-bit sigma-delta ADC, and I²C-compatible digital core with programmable conversion period (31.25 ms to 2 s), adjustable averaging (0–8 samples), and dual alert thresholds with hysteresis (0.1°C). It operates across –40°C to 125°C with supply voltage independence for logic inputs (1.2 V compatible regardless of VDD).
Its functional architecture supports continuous or one-shot conversion modes, optional CRC-8 for data integrity, slew-rate warning detection (±15% accuracy), and NIST-traceable calibration performed on production test equipment - enabling reliable thermal monitoring without external compensation or post-manufacturing trimming.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital temperature sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX31875R2+T | ±0.25°C accuracy (–20°C to 100°C); 1.71–3.6 V supply; 0.8 µA avg current; same 4-ball WLP package | Higher supply range suits industrial sensors; lacks slew-rate warning and NIST traceability | Preferred where wider voltage tolerance outweighs need for ultra-low-height packaging or pre-certified calibration |
| STTS22H | ±0.5°C accuracy (–20°C to 85°C); 1.7–3.6 V supply; 0.5 µA avg current; 1.5 mm × 1.5 mm DFN | Larger footprint; no CRC or adjustable hysteresis; lower accuracy but higher ESD rating (±4 kV HBM) | Selected when board space permits larger package and cost sensitivity overrides sub-0.3°C accuracy requirements |
Compared with TMP114DIYMTR, MAX31875R2+T offers broader supply flexibility but omits NIST traceability and ultra-thin packaging, while STTS22H trades accuracy and height for higher ESD robustness and lower unit cost - making TMP114DIYMTR optimal for premium portable electronics demanding metrology-grade thermal data in minimal volume.

FAQ
What is the maximum operating temperature range for the TMP114DIYMTR?
The TMP114DIYMTR operates across –40°C to 125°C. Its accuracy specification is tiered: ±0.2°C maximum from 20°C to 50°C, ±0.3°C from –10°C to 80°C, and ±0.5°C from –40°C to 125°C. This full-range capability makes TMP114DIYMTR suitable for automotive cabin modules, industrial SSDs, and outdoor IP cameras where ambient extremes are expected.
Does the TMP114DIYMTR require external calibration after soldering?
No, the TMP114DIYMTR does not require external calibration. Each unit undergoes factory calibration on a NIST-traceable production test system compliant with ISO/IEC 17025 standards. The device retains its ±0.2°C accuracy specification post-reflow, eliminating system-level trim routines and reducing firmware development overhead for TMP114DIYMTR integration.
How does the TMP114DIYMTR achieve 1.2-V logic compatibility while operating down to 1.08 V?
The TMP114DIYMTR uses static input threshold circuitry on SDA and SCL pins, decoupling logic recognition levels from VDD. VIH is fixed at 0.84 V (min) and VIL at 0.35 V (max), enabling reliable communication with 1.2-V I²C masters even when VDD = 1.08 V - a key enabler for TMP114DIYMTR use in heterogeneous voltage domains common in modern SoC subsystems.
Can the TMP114DIYMTR be used on an I³C bus alongside I²C devices?
Yes, the TMP114DIYMTR includes a 50-ns spike filter on SDA and SCL lines, allowing it to coexist on mixed I³C/I²C buses without false triggering from I³C-specific signaling artifacts. While TMP114DIYMTR itself is I²C/SMBus-only (not I³C-capable), its hardened interface ensures deterministic behavior in shared-bus environments typical in mobile and notebook platforms.
What is the significance of the 0.15-mm package height for TMP114DIYMTR placement?
The 0.15-mm PicoStar DSBGA height enables TMP114DIYMTR to be placed directly beneath other surface-mount components - such as RF shields or camera modules - minimizing thermal conduction path length and reducing measurement lag. This physical integration advantage is critical for achieving fastest possible thermal response in space-constrained designs using TMP114DIYMTR.
