Product details
Overview
TMP114NDIYMTR from Texas Instruments is a high-accuracy 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 ultra-thin 4-ball DSBGA (PicoStar) package (0.76 mm × 0.76 mm, 0.15 mm height). It operates from 1.08 V to 1.98 V and delivers <0.7 µA average current in continuous 1-Hz conversion mode - ideal for space-constrained thermal monitoring in mobile and wearable electronics.
For engineers reviewing the TMP114NDIYMTR datasheet, TMP114NDIYMTR pinout, TMP114NDIYMTR application, or TMP114NDIYMTR equivalent, this page provides verified technical context, pin-level design meaning, real-world use cases with IC role clarity, and two validated alternative parts with documented functional and application differences.
Technical Context
The TMP114NDIYMTR integrates a factory-calibrated bandgap-based temperature sensing element with a 16-bit sigma-delta ADC and on-chip digital signal processing. Its I²C interface supports Standard, Fast, and Fast-Plus modes (up to 1 MHz), includes optional CRC-8 for data integrity, and features 1.2-V-compatible logic thresholds independent of supply voltage.
It implements three alert mechanisms: programmable high/low temperature limits with hysteresis, slew-rate warning for rapid thermal transients (±15% accuracy), and NIST-traceable calibration across –40°C to 125°C. Conversion timing is configurable (6.4 ms to 51.2 ms), with averaging and one-shot or continuous operation modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Accuracy | ±0.2°C max (20°C–50°C); ±0.3°C max (–10°C–80°C); ±0.5°C max (–40°C–125°C) - enables precise thermal throttling in battery-powered devices |
| Resolution | 16-bit (0.0078°C LSB) - supports fine-grained temperature trending for predictive thermal management |
| Supply Range | 1.08 V to 1.98 V - compatible with modern low-voltage SoCs and PMIC rails without level-shifting |
| Average Current | 0.63 µA (typ, 1 Hz, 25°C, no averaging) - extends battery life in always-on wearables and IoT edge nodes |
| Response Time | 300 ms (τ = 63%, stirred liquid, flex PCB) - enables fast thermal event detection in compact assemblies |
| I²C Compatibility | Standard/Fast/Fast-Plus modes; 50 ns spike filter - coexists reliably on mixed-signal I³C/I²C buses |

Pinout & Package
Package: 4-ball DSBGA (PicoStar), 0.76 mm × 0.76 mm footprint, 0.15 mm profile - optimized for volume-constrained placement beneath other SMT components.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | Accepts 1.08–1.98 V; powers internal analog/digital blocks; requires local 0.1 µF decoupling |
| GND | Ground reference | Return path for all currents; must be connected to system ground plane with low-inductance trace |
| SDA | Open-drain bidirectional data line | I²C data line with integrated 50 ns glitch filter; requires external pull-up (1.2 kΩ typical) to same or higher voltage rail |
| SCL | Input-only clock line | I²C clock input with 1.2-V-compatible threshold; tolerant of 0–1.98 V logic swing regardless of VDD |
Key Features
| Feature | Design Value |
|---|---|
| NIST-traceable calibration | Each unit tested on ISO/IEC 17025-accredited setup - eliminates need for system-level recalibration in medical or industrial applications |
| Adjustable slew-rate warning | Detects rapid temperature rise (e.g., CPU burst load) before crossing thermal limits - enables proactive power scaling instead of reactive throttling |
| Configurable averaging & conversion period | 8-sample averaging reduces noise by ~2.8×; conversion interval adjustable from 31.25 ms to 2 s - balances resolution, latency, and power |
| Programmable alert hysteresis | Hysteresis up to ±0.1°C prevents chattering at trip points during slow thermal transitions - stabilizes fan control or shutdown logic |
| CRC-8 data integrity | Optional 8-bit CRC over address, register pointer, and data - ensures robust communication in electrically noisy environments (e.g., near RF transceivers) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital temperature sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMP117AIYBGT | Higher accuracy (±0.1°C from –20°C to 50°C); 2.5-mm × 2.5-mm WSON-8 package; 1.7-V to 3.6-V supply | Requires PCB area increase (~6.25× footprint) and higher minimum supply voltage - unsuitable for sub-1.2-V systems or ultra-thin stacks | Select when ±0.1°C accuracy is mandatory and board space allows larger package; not drop-in for TMP114NDIYMTR layouts |
| MAX31875R12+T | ±0.25°C accuracy (–40°C to +125°C); 1.5-mm × 1.5-mm WLP-6; I²C interface; 1.7-V to 3.6-V supply | Larger footprint (1.5 mm × 1.5 mm vs. 0.76 mm × 0.76 mm); no slew-rate warning or NIST traceability; lower power only below 1.7 V | Choose for cost-sensitive designs where ultra-thin profile is secondary and NIST traceability is not required |
Compared with TMP114NDIYMTR, TMP117AIYBGT offers tighter accuracy but demands significantly more board area and higher voltage, while MAX31875R12+T trades ultra-thin packaging and NIST validation for lower cost - making TMP114NDIYMTR uniquely suited for space- and voltage-constrained, high-integrity thermal sensing.

FAQ
What is the maximum operating temperature range for the TMP114NDIYMTR?
The TMP114NDIYMTR operates across –40°C to +125°C ambient temperature. Its accuracy specification is tiered: ±0.2°C max from 20°C to 50°C, ±0.3°C max from –10°C to 80°C, and ±0.5°C max over the full –40°C to 125°C range. This makes TMP114NDIYMTR suitable for both consumer and extended industrial environments where thermal extremes occur.
Does the TMP114NDIYMTR support I²C Fast-Plus mode?
Yes, the TMP114NDIYMTR supports I²C Fast-Plus mode up to 1 MHz, as confirmed in Section 7.6 of the official datasheet. It meets timing requirements for t(LOW), t(HIGH), t(SUDAT), and t(HDDAT) at VDD = 1.08 V to 1.98 V and –40°C to 125°C. This enables high-speed polling in systems with tight thermal response deadlines.
How does the slew-rate warning function in the TMP114NDIYMTR?
The TMP114NDIYMTR's slew-rate warning detects rapid temperature changes by comparing consecutive readings in continuous mode. When the positive delta exceeds the user-programmed Slew_Limit register value, it sets the Slew_Flag and Slew_Status bits. Accuracy is ±15% due to oscillator variation, and the feature auto-disables in shutdown mode - providing early thermal anomaly detection before critical limits are breached.
Is the TMP114NDIYMTR NIST-traceable, and what does that mean for system design?
Yes, each TMP114NDIYMTR is 100% tested on a production setup calibrated to NIST standards per ISO/IEC 17025. This means its ±0.2°C accuracy is verified at the device level without requiring end-system re-trimming - reducing qualification time and eliminating calibration overhead in medical, industrial, and automotive thermal subsystems.
What is the physical package size and height of the TMP114NDIYMTR?
The TMP114NDIYMTR uses a 4-ball DSBGA (PicoStar) package measuring 0.76 mm × 0.76 mm with a nominal height of 0.15 mm. This ultra-thin profile allows placement under cameras, displays, or shields - enabling direct thermal coupling to heat sources while minimizing PCB footprint and Z-height constraints in slim mobile and wearable form factors.
