Product details
Overview
TMP114NAIYMTR 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 phone thermal management and SSD die temperature monitoring.
For engineers reviewing the TMP114NAIYMTR datasheet, TMP114NAIYMTR pinout, TMP114NAIYMTR application, or TMP114NAIYMTR equivalent, key selection criteria include NIST-traceable accuracy across –40°C to 125°C, 1.08 V–1.98 V supply compatibility, 300 ms liquid response time, and 4-ball DSBGA package height of only 0.15 mm for space-constrained placement under components.
Technical Context
The TMP114NAIYMTR integrates a factory-calibrated bandgap-based thermal sensing element with a 16-bit sigma-delta ADC and on-chip oscillator, delivering temperature data via I²C with optional CRC-8 for data integrity. Its static 1.2-V logic thresholds on SDA/SCL enable interoperability with 1.2-V or 1.8-V buses independent of VDD.
It supports continuous and one-shot conversion modes, adjustable averaging (1× or 8×), programmable conversion periods (31.25 ms to 2 s), and dual alert mechanisms: threshold-based temperature limits with hysteresis and slew-rate warning for rapid thermal transients - all configurable via its 8-register map.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital temperature sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMP103YFFT | ±1°C accuracy (–40°C to 125°C); 6-bit resolution; no slew-rate warning or CRC | Limited to cost-sensitive consumer devices where ±0.2°C precision is not required | Select when budget constraints outweigh need for NIST traceability and advanced alert features |
| MAX31875R2+ | ±0.25°C accuracy (0°C–70°C); 16-bit resolution; SMBus-only; no 1.2-V logic compatibility | Requires 1.8-V I/O rail; lacks ultra-thin package and I³C coexistence capability | Prefer for industrial systems with stable 1.8-V buses and no space constraints |
Compared with TMP114NAIYMTR, TMP103YFFT trades accuracy and feature depth for lower unit cost, while MAX31875R2+ matches resolution but lacks the 0.15-mm profile and 1.2-V logic support critical for mobile and wearable integration.

FAQ
What is the maximum operating temperature range for the TMP114NAIYMTR?
The TMP114NAIYMTR operates across –40°C to +125°C. Its accuracy specification is tiered: ±0.2°C from 20°C to 50°C, ±0.3°C from –10°C to 80°C, and ±0.5°C over the full –40°C to 125°C range. This makes TMP114NAIYMTR suitable for both consumer and industrial thermal monitoring where extended range reliability is required.
Does the TMP114NAIYMTR support I²C Fast Mode Plus (1 MHz)?
Yes, the TMP114NAIYMTR supports I²C Fast Mode Plus up to 1 MHz, as confirmed in Section 7.6 of the datasheet. It meets timing requirements including tLOW, tHIGH, and tVDAT at 1 MHz across –40°C to 125°C and 1.08 V–1.98 V supply, enabling high-speed thermal polling in bandwidth-constrained systems using TMP114NAIYMTR.
How does the slew-rate warning function in the TMP114NAIYMTR?
The TMP114NAIYMTR's slew-rate warning compares the difference between consecutive temperature readings against a user-programmed Slew_Limit register value. When exceeded, it sets the Slew_Flag and Slew_Status bits in the Alert_Status register. The feature operates only in continuous mode and has ±15% accuracy due to oscillator variation - a verified behavior of TMP114NAIYMTR used for proactive thermal event detection.
Is the TMP114NAIYMTR pin-compatible with other TMP114 variants like TMP114NA or TMP114B?
No - TMP114NAIYMTR is the TMP114N variant with I²C address 1001111 (0x4F), whereas TMP114B uses address 1001001 (0x49). All TMP114 variants share identical 4-ball DSBGA (YMT) packaging and pinout, but differ in accuracy grade and I²C address. Hardware layout remains unchanged across variants, though firmware must configure the correct address for TMP114NAIYMTR.
What is the significance of NIST traceability for the TMP114NAIYMTR?
NIST traceability means each TMP114NAIYMTR is calibrated on production test equipment validated against standards accredited to ISO/IEC 17025. This provides documented metrological confidence in its ±0.2°C accuracy - eliminating the need for system-level recalibration and supporting compliance in regulated applications. The TMP114NAIYMTR datasheet explicitly states this traceability applies to all production units.
