Overview

The TMP117AIDRVR is a high-precision digital temperature sensor that provides 16-bit resolution with an accuracy of up to 0.1 degrees Celsius. It is designed to meet medical standards like ISO 80601-2-56 and ASTM E1112, making it a viable solid-state replacement for traditional RTDs. The device operates over a wide 1.7V to 5.5V range and consumes only 3.5 microamps at a 1-Hz conversion rate, ideal for battery-powered systems.

Why Choose This Part

The TMP117 stands out for its NIST-traceable accuracy without the complexity of analog signal conditioning or multi-point calibration. It features ultra-low power consumption and integrated EEPROM for system configuration or tracking. Its compact 2x2mm WSON package and I2C/SMBus interface allow for easy integration into space-constrained board designs.

Applications

Medical Thermometry
High-accuracy clinical thermometers and wearable body temperature monitors meeting medical grade standards.
Environmental Monitoring
Precision HVAC controls and weather stations requiring high-resolution thermal data.
RTD Replacement
A digital alternative to PT100 or PT1000 sensors, eliminating the need for precision ADCs or calibration.
Cold Chain Logistics
Monitoring sensitive pharmaceuticals or food products during transport and storage.

Getting Started

To evaluate this sensor, the TMP117EVM evaluation module can be used with TI-supplied software. Engineers should ensure the thermal pad is correctly soldered to a large copper area for optimal thermal response time, though isolation may be needed if measuring ambient air. Implementation involves standard I2C communication to read the 16-bit temperature register and optionally configuring the 48-bit general-purpose EEPROM.
