Product details
Overview
TMP114NAIYMTT from Texas Instruments is a high-accuracy, ultra-thin digital temperature sensor with I²C/SMBus interface, ±0.2°C accuracy from 20°C to 50°C, 16-bit resolution (0.0078°C LSB), and operation from 1.08 V to 1.98 V supply - deployed in mobile phones and SSDs for real-time thermal monitoring.
For engineers reviewing the TMP114NAIYMTT datasheet, TMP114NAIYMTT pinout, TMP114NAIYMTT application, or TMP114NAIYMTT equivalent, key selection criteria include its 0.15-mm DSBGA package height, NIST-traceable calibration, 300-ms liquid response time, 0.7 µA average current in continuous mode, and 1.2-V logic compatibility independent of VDD.
Technical Context
The TMP114NAIYMTT integrates a precision bandgap-based thermal sensing element with a 16-bit sigma-delta ADC and on-chip oscillator, delivering factory-calibrated output without external compensation. Its digital core supports both continuous and one-shot conversion modes, with configurable averaging (AVG=0/1) and conversion periods ranging from 31.25 ms to 2 s.
It implements an optional 8-bit CRC for I²C data integrity, slew-rate warning detection using consecutive temperature deltas, and dual alert thresholds with programmable hysteresis. The device uses static 1.2-V-compatible input thresholds on SDA/SCL, enabling interoperability across mixed-voltage I²C buses without level shifters.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital temperature sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMP117AIYFFR | ±0.1°C max accuracy (0°C–70°C); 32-bit resolution; 0.8-mm × 0.8-mm DSBGA; 1.7-µA avg current | Higher precision required for medical-grade thermometry; larger footprint and higher power limit use in ultra-thin wearables | Select TMP117AIYFFR only if sub-0.2°C accuracy and long-term drift <0.01°C/year are mandatory |
| MAX31875CATB+ | ±1.0°C accuracy; 12-bit resolution; 1.5-mm × 1.5-mm WLP; supports SMBus Alert Response Address | Lower-cost thermal protection in industrial controllers where ±1°C tolerance is acceptable | Choose MAX31875CATB+ when cost sensitivity outweighs accuracy needs and board space permits larger package |
Compared with TMP114NAIYMTT, TMP117AIYFFR delivers tighter accuracy but increases average current by 2.7× and raises BOM cost; MAX31875CATB+ reduces cost and simplifies alert handling but sacrifices 0.8°C absolute accuracy and 4-bit resolution - making TMP114NAIYMTT optimal for space-constrained, battery-sensitive consumer electronics requiring verified ±0.2°C performance.

FAQ
What is the operating temperature range of the TMP114NAIYMTT?
The TMP114NAIYMTT operates across –40°C to +125°C. Within this full range, its accuracy is specified as ±0.5°C maximum; tighter tolerances apply in narrower bands: ±0.2°C from 20°C to 50°C and ±0.3°C from –10°C to 80°C. This graded specification reflects factory calibration across multiple temperature points using NIST-traceable equipment, ensuring reliable thermal feedback in both ambient and high-stress environments where the TMP114NAIYMTT is deployed.
Does the TMP114NAIYMTT support I²C Fast Mode Plus timing?
Yes, the TMP114NAIYMTT supports I²C Fast Mode Plus with up to 1 MHz clock frequency (fSCL), meeting tLOW/tHIGH ≤ 0.26 µs and tVDAT ≤ 150 ns requirements. It also includes a 50-ns spike filter on SDA/SCL lines, enabling robust coexistence on mixed-signal I³C buses. The device maintains static 1.2-V logic thresholds regardless of VDD, allowing seamless interface with 1.2-V or 1.8-V controllers - a key capability confirmed in the TMP114NAIYMTT's official timing tables and functional description.
How does the TMP114NAIYMTT achieve ±0.2°C accuracy without system-level calibration?
The TMP114NAIYMTT achieves ±0.2°C accuracy through 100% production testing on a NIST-traceable setup compliant with ISO/IEC 17025, including on-chip trimming of offset and gain errors across temperature. Its bandgap-based thermal sensing element and 16-bit sigma-delta ADC are characterized and compensated at wafer and final test stages. No external calibration is needed because the TMP114NAIYMTT delivers factory-trimmed digital output - a capability explicitly validated in TI's SNIS214E datasheet revision history and electrical characteristics section.
Can the TMP114NAIYMTT be used in one-shot mode to minimize power consumption?
Yes, the TMP114NAIYMTT supports one-shot mode via the OS bit in its Configuration register. When triggered, it performs a single temperature conversion (6.4 ms typical with averaging off) then automatically enters shutdown mode, drawing only 0.16 µA (TYP). This mode is ideal for event-driven thermal sampling - for example, waking from deep sleep to measure temperature once per minute. The TMP114NAIYMTT's datasheet confirms this behavior in Section 8.4.2.1 and specifies shutdown current across –40°C to +125°C.
What package type and dimensions does the TMP114NAIYMTT use?
The TMP114NAIYMTT uses a 4-ball DSBGA (PicoStar™) package measuring 0.76 mm × 0.76 mm with a 0.15-mm maximum height. This ultra-thin profile enables placement under other surface-mount components or within tight flex-rigid stackups. Pin layout is VDD (A1), GND (A2), SDA (B1), SCL (B2) - confirmed in Figure 6-1 and Table 6-1 of the TMP114NAIYMTT datasheet, with solder ball pitch of 0.4 mm and JEDEC-standard footprint.
