Texas Instruments TMP117NAIYBGT

Overview

TMP117NAIYBGT from Texas Instruments is a high-accuracy, low-power digital temperature sensor with SMBus™- and I²C-compatible interface, ±0.1 °C max accuracy from –20 °C to 50 °C, 16-bit resolution (0.0078 °C/LSB), and operating range of –55 °C to 150 °C - deployed in electronic thermometers, cold chain asset tracking, and medical-grade patient monitoring systems.

For engineers reviewing the TMP117NAIYBGT datasheet, TMP117NAIYBGT pinout, TMP117NAIYBGT application, or TMP117NAIYBGT equivalent, key selection considerations include NIST-traceable calibration, programmable alert thresholds, 48-bit general-purpose EEPROM, medical compliance (ASTM E1112 / ISO 80601-2-56), and RTD replacement capability for PT100/PT1000 systems.

Technical Context

The TMP117NAIYBGT integrates a precision bandgap-based thermal sensing element with a 16-bit sigma-delta ADC and on-chip oscillator, delivering factory-calibrated temperature data without external compensation. Its digital architecture supports I²C/SMBus communication at up to 400 kHz with open-drain SDA/ALERT pins and address-selectable ADD0 pin.

It operates in multiple functional modes - continuous conversion, one-shot, and shutdown - with configurable averaging (1–8 samples) and programmable temperature alert limits stored in dedicated registers. The device uses two's complement 16-bit output format and includes 48 bits of user-accessible EEPROM for system-level offset correction and configuration storage.

FAQ

What is the maximum accuracy specification of the TMP117NAIYBGT over its full operating temperature range?

The TMP117NAIYBGT achieves ±0.3 °C maximum accuracy from –55 °C to +150 °C. Within the narrower clinical range of –20 °C to +50 °C, its accuracy tightens to ±0.1 °C - verified across 100% of production units using NIST-traceable test equipment calibrated to ISO/IEC 17025 standards. This performance is guaranteed without end-user calibration.

Does the TMP117NAIYBGT support medical-grade compliance for electronic patient thermometers?

Yes, the TMP117NAIYBGT meets ASTM E1112 and ISO 80601-2-56 requirements for electronic patient thermometers. It is explicitly qualified for clinical use, with full documentation of test methodology, uncertainty budgets, and traceability to national standards - enabling faster regulatory submission for Class II medical devices incorporating the TMP117NAIYBGT.

How does the TMP117NAIYBGT replace traditional platinum RTD sensors like PT100?

The TMP117NAIYBGT matches Class AA PT100 accuracy while eliminating excitation current, precision reference circuits, and complex linearization. Unlike PT100s requiring 1–2 mA excitation and matched PCB traces, the TMP117NAIYBGT draws only 3.5 μA in active mode and outputs calibrated digital temperature directly - reducing BOM count, layout complexity, and power consumption by >99% compared to discrete RTD solutions.

What package type and dimensions does the TMP117NAIYBGT use?

The TMP117NAIYBGT uses a 6-pin DSBGA (YBG) package measuring 1.53 mm × 1.00 mm with 0.4-mm pitch and an exposed thermal pad on the bottom. This ultra-compact, low-profile package is optimized for space-constrained applications such as wearable patches and miniature medical probes - and is distinct from the larger WSON (DRV) variant used in other TMP117 part numbers.

Can the TMP117NAIYBGT operate from a 1.8-V supply across its full temperature range?

Yes, the TMP117NAIYBGT supports 1.8 V to 5.5 V supply voltage across its full operating range of –55 °C to +150 °C. At 1.8 V, it maintains full functionality including 16-bit conversion, programmable alerts, EEPROM access, and I²C communication - enabling direct integration with modern ultra-low-voltage MCUs and energy-harvesting systems without level-shifting.
