Product details
Overview
TMP116NAIDRVT from Texas Instruments is a high-accuracy, low-power digital temperature sensor with SMBus- and I²C-compatible interface, delivering ±0.3°C max accuracy from –25°C to +85°C and ±0.4°C from –40°C to +125°C, 16-bit resolution (0.0078°C/LSB), and 3.5-μA active current at 1-Hz conversion cycle - used in medical-grade thermostats, wearables, and cold-chain asset tracking.
For engineers reviewing the TMP116NAIDRVT datasheet, TMP116NAIDRVT pinout, TMP116NAIDRVT application, or TMP116NAIDRVT equivalent, key selection criteria include its NIST-traceable calibration, programmable alert limits, on-chip EEPROM (64 bits), selectable averaging (1/8/16/32 samples), and operation across 1.9 V–5.5 V supply range without external components.
Technical Context
The TMP116NAIDRVT implements a precision sigma-delta ADC with internal reference and thermal sensing element, supporting continuous, one-shot, and shutdown functional modes via MOD[1:0] register control. Its digital core includes configurable averaging logic, dual alert limit registers, and Data_Ready flag management synchronized to conversion completion.
It operates over –55°C to +125°C junction temperature, uses two-wire timing compliant with 400-kHz I²C Fast Mode, and features open-drain SDA/ALERT outputs requiring external pullups. The ALERT pin supports both data-ready indication and overtemperature window detection with polarity-selectable output via POL bit.
Key Specifications

FAQ
What is the maximum operating temperature range for the TMP116NAIDRVT?
The TMP116NAIDRVT operates across a junction temperature range of –55°C to +125°C, with specified accuracy of ±0.4°C from –40°C to +125°C. This makes the TMP116NAIDRVT suitable for under-hood automotive, industrial motor drives, and outdoor environmental monitoring where extreme thermal conditions occur.
Does the TMP116NAIDRVT require external calibration to achieve its stated accuracy?
No, the TMP116NAIDRVT does not require external calibration. It is factory tested on NIST-traceable, ISO/IEC 17025-accredited equipment and delivers ±0.3°C accuracy from –25°C to +85°C and ±0.4°C from –40°C to +125°C out-of-box - meeting ASTM and ISO medical standards without user calibration.
How does the TMP116NAIDRVT reduce measurement noise in electrically noisy environments?
The TMP116NAIDRVT reduces noise through hardware-selectable averaging (1/8/16/32 samples), which lowers repeatability error from ±3 LSB to ±1 LSB. This feature is configured via the AVG[1:0] bits and executed entirely within the device - eliminating software filtering overhead and improving thermal stability in EMI-prone applications like motor controllers.
Can the TMP116NAIDRVT replace RTD sensors such as PT100 in temperature measurement systems?
Yes, the TMP116NAIDRVT can replace PT100, PT500, and PT1000 RTDs in many applications. It exceeds Class A RTD accuracy across –40°C to +125°C while consuming less than 20% of typical RTD excitation current and eliminating bridge circuitry, matched PCB traces, and Kelvin connections - simplifying design and reducing BOM cost.
What is the function of the ADD0 pin on the TMP116NAIDRVT?
The ADD0 pin on the TMP116NAIDRVT sets the least significant bit of the I²C slave address. When grounded, it configures the address to 0x48; when tied to V+, SDA, or SCL, it sets the address to 0x49 - enabling up to two TMP116NAIDRVT devices on the same bus without address conflict or external level-shifting components.
