Product details
Overview
TMP117MAIYBGT 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 wearable fitness monitors.
For engineers reviewing the TMP117MAIYBGT datasheet, TMP117MAIYBGT pinout, TMP117MAIYBGT application, or TMP117MAIYBGT equivalent, key selection considerations include medical-grade ASTM E1112/ISO 80601-2-56 compliance, NIST-traceable calibration, programmable alert thresholds, 48-bit general-purpose EEPROM, and DSBGA-6 (1.53 mm × 1.00 mm) package suitability for space-constrained thermal sensing.
Technical Context
The TMP117MAIYBGT integrates a precision bandgap-based thermal sensor front-end, 16-bit sigma-delta ADC, and two-wire interface logic supporting standard-mode (100 kHz) and fast-mode (400 kHz) I²C/SMBus protocols. It features factory-programmed NIST-traceable calibration coefficients stored in on-chip EEPROM.
Its functional architecture includes configurable averaging (1/2/4/8 conversions), digital offset correction, programmable high/low temperature alert limits, and dual operational modes: continuous conversion (MOD[1:0] = 00/10) and one-shot (MOD[1:0] = 01/11), with active current as low as 3.5 μA at 1-Hz duty cycle.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital temperature sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX30205 | ±0.1 °C accuracy (0 °C to 50 °C), 16-bit resolution, but only rated to 50 °C max operating temperature | Limited to non-industrial medical wearables; lacks NIST traceability and EEPROM | Choose when cost sensitivity outweighs extended temperature range and calibration documentation requirements |
| STS35-DIS | ±0.1 °C accuracy (15 °C to 45 °C), SMD-8 package (2.5 mm × 2.5 mm), no integrated EEPROM | Requires external memory for configuration storage; not certified to ASTM E1112 | Prefer for high-volume consumer electronics where medical certification is unnecessary and board space permits larger footprint |
Compared with MAX30205 and STS35-DIS, the TMP117MAIYBGT uniquely combines full medical certification, extended –55 °C to 150 °C operation, on-chip EEPROM, and NIST-traceable calibration - making it the only option qualified for regulated clinical thermometry and high-reliability industrial logging without external support components.

FAQ
What is the maximum operating temperature specification for the TMP117MAIYBGT?
The TMP117MAIYBGT is specified for continuous operation from –55 °C to 150 °C. Its absolute maximum junction temperature is 155 °C, and thermal performance is characterized with RθJA = 133.2 °C/W for the YBG (DSBGA-6) package. This extended range supports use in automotive under-hood modules, industrial motor drives, and sterilization equipment where ambient temperatures exceed 100 °C - confirmed in TI's SNOSD82D datasheet Section 6.3.
Does the TMP117MAIYBGT require external calibration to achieve its stated ±0.1 °C accuracy?
No, the TMP117MAIYBGT does not require external calibration to achieve ±0.1 °C accuracy from –20 °C to 50 °C. Each unit undergoes 100% production testing on a NIST-traceable setup calibrated to ISO/IEC 17025 standards, and factory-programmed calibration coefficients are stored in on-chip EEPROM. The TMP117MAIYBGT delivers this accuracy out-of-box, as verified in Section 6.5 of the official datasheet.
How many TMP117MAIYBGT devices can share the same I²C bus?
Up to four TMP117MAIYBGT devices can operate on a single I²C bus. This is enabled by the ADD0 pin, which selects one of four unique slave addresses (0x48–0x4B) depending on whether it is tied to GND, V+, SDA, or SCL. Bus arbitration and timing comply with standard-mode (100 kHz) and fast-mode (400 kHz) I²C specifications - detailed in Sections 5 and 6.7 of the TMP117MAIYBGT datasheet.
What is the function of the ALERT pin on the TMP117MAIYBGT?
The ALERT pin on the TMP117MAIYBGT is an open-drain output that signals either temperature threshold violation (programmed via THIGH/ TLOW registers) or data-ready status (when DR/nAlert_EN bit is set). It requires an external pullup resistor (typically 4.7 kΩ) and operates across the full supply range (1.8–5.5 V). Its sink capability is specified at 3 mA with VOL ≤ 0.4 V - enabling direct connection to most microcontroller interrupt inputs without level-shifting.
Is the TMP117MAIYBGT suitable as a direct replacement for PT100 RTD sensors?
Yes, the TMP117MAIYBGT is explicitly positioned as an RTD replacement, matching Class AA PT100 accuracy (±0.1 °C at 0 °C) while eliminating the need for precision excitation current sources, matched PCB traces, and complex linearization algorithms. Unlike PT100s, the TMP117MAIYBGT provides direct digital output, consumes <1% of the power, and integrates EEPROM for system-specific offset correction - as confirmed in the "RTDs replacement" section of the official datasheet.
