Texas Instruments TMP116AIDRVT

Overview

TMP116AIDRVT from Texas Instruments is a high-accuracy, low-power digital temperature sensor with SMBus- and I²C-compatible interface, delivering ±0.2°C max accuracy from –10°C to +85°C, 16-bit resolution (0.0078°C/LSB), and operation across –55°C to +125°C. It serves as a precision thermal monitoring device in medical, wearables, and cold-chain systems where calibration-free operation and NIST-traceable accuracy are critical.

For engineers reviewing the TMP116AIDRVT datasheet, TMP116AIDRVT pinout, TMP116AIDRVT application, or TMP116AIDRVT equivalent, this page delivers verified technical context, real-world design meaning for key specs, validated pin functions, confirmed alternative options, and supply-ready availability details - all grounded in TI's production-grade SBOS740A specification.

Technical Context

The TMP116AIDRVT integrates a precision bandgap-based temperature transducer, 16-bit sigma-delta ADC, and programmable alert logic with dual limit registers. Its conversion architecture supports one-shot, continuous, and shutdown modes, with configurable averaging (1/8/16/32 samples) to reduce noise while scaling active time linearly.

It implements a two-wire interface compliant with I²C Fast Mode (400 kHz) and SMBus 3.0, featuring open-drain SDA/ALERT pins with 3.5 µA active current (1-Hz cycle, no averaging) and 250 nA shutdown current. The device uses factory-programmed EEPROM for configuration persistence and supports up to four devices on a single bus via ADD0 address selection.

FAQ

What is the maximum accuracy specification of the TMP116AIDRVT over its full operating range?

The TMP116AIDRVT achieves ±0.2°C maximum accuracy from –10°C to +85°C, ±0.25°C from –40°C to +105°C, and ±0.3°C from +105°C to +125°C. At the full –55°C to +125°C range under 1.9–5.5 V supply, accuracy degrades to ±0.4°C. These values are production-tested and NIST-traceable per TI's SBOS740A datasheet.

Does the TMP116AIDRVT require external calibration to meet its published accuracy?

No, the TMP116AIDRVT does not require external calibration. Its ±0.2°C accuracy from –10°C to +85°C is guaranteed at wafer and final test using TI's NIST-traceable production setup, verified against ISO/IEC 17025-accredited equipment. System-level calibration is unnecessary for most medical and industrial applications.

How does the TMP116AIDRVT manage power in battery-operated systems?

The TMP116AIDRVT supports multiple low-power modes: 3.5 µA quiescent current in 1-Hz active conversion, 1.25 µA in standby, and just 250 nA in shutdown mode. Its one-shot mode allows precise on-demand measurements without sustained current draw - enabling multi-year operation on CR2032 cells in wearables and trackers.

Can the TMP116AIDRVT replace traditional RTDs like PT100 in industrial metering?

Yes, the TMP116AIDRVT exceeds Class A RTD accuracy across –40°C to +125°C while consuming less than 20% of the excitation current required by a PT100. It eliminates matched traces, Kelvin connections, and external signal conditioning - reducing BOM cost and PCB area versus RTD-based solutions in gas meters and heat cost allocators.

What interface protocols does the TMP116AIDRVT support, and what are its timing limits?

The TMP116AIDRVT supports standard I²C and SMBus protocols, operating up to 400 kHz (Fast Mode). Key timing parameters include tLOW ≥1300 ns, tHIGH ≥600 ns, and tSU;DAT ≥100 ns. It also implements SMBus Alert Response and timeout recovery (20–40 ms), ensuring robust communication in noisy industrial buses.
