Overview

The TMP117NAIDRVR is a high-precision digital temperature sensor providing 16-bit resolution and an accuracy of up to +/-0.1 degrees Celsius. It operates over a wide supply range of 1.7V to 5.5V and features an integrated EEPROM for system configuration and user-defined data. This sensor is specifically designed to meet medical standards such as ASTM E1112 and ISO 80601-2-56 while maintaining ultra-low power consumption.

Why Choose This Part

The sensor offers NIST-traceable accuracy without the need for complex system-level calibration or heavy software processing. Its ultra-low power profile and small 2x2mm WSON package make it ideal for space-constrained, battery-operated IoT devices. Additionally, the programmable alert limits and selectable averaging allow for flexible hardware-level thermal management.

Applications

Medical Thermometers
Meets clinical accuracy requirements for body temperature monitoring in wearables and digital thermometers.
Environmental Monitoring
Utilizes 1.25 microamp sleep current to extend battery life in remote wireless sensor nodes.
RTD Replacement
Provides a solid-state alternative to PT100 and PT1000 platinum resistance temperature detectors with a smaller footprint and simpler digital interface.
Industrial Instrumentation
Delivers high-precision thermal data for calibration equipment and sensitive process control loops.

Getting Started

Interface the TMP117 via its I2C or SMBus pins to any standard microcontroller; TI provides the TMP117EVM evaluation module for rapid prototyping. In hardware layout, use thin traces and thermal reliefs to isolate the sensor from heat-generating components like MCUs or LDOs. Use the integrated 48-bit EEPROM to store persistent calibration offsets or device identification strings.
