In the fields of medical equipment, industrial automation, and automotive electronics testing, the accuracy and stability of temperature measurement are key indicators of system performance. While traditional PT100/PT1000 platinum resistance temperature sensors offer acceptable accuracy, they often require complex signal conditioning circuits, consume high power, and entail expensive calibration costs.
To address this industry challenge, Texas Instruments has introduced the TMP117AIDRVR—a digital temperature sensor that integrates a high-precision ADC and EEPROM. As a professional provider of electronic component solutions, [Shenzhen Mingjiada Electronics] now offers genuine TMP117AIDRVR units in stock to help customers accelerate their time-to-market.
Key Highlights: Medical-Grade Accuracy of ±0.1°C
The TMP117AIDRVR is not just a temperature sensor; it is a powerful single-chip solution designed to replace PT100 RTDs. Its technical specifications offer overwhelming advantages over traditional solutions:
Extremely High Accuracy:
Across a wide temperature range of -20°C to +50°C, this sensor achieves measurement accuracy of up to ±0.1°C, meeting the ASTM E1112 and ISO 80601 standards for medical electronic thermometers without the need for calibration.
Ultra-low power consumption:
Power consumption is critical in the design of portable devices (such as smartwatches and cold chain loggers). The TMP117 typically draws only 3.5 µA during operation (at a 1 Hz sampling rate), with a shutdown current as low as 150 nA, significantly extending battery life.
Convenience of Digitalization:
Compared to PT100, which requires complex differential amplifier circuits and ADC drivers, the TMP117 communicates via a standard I²C interface and directly outputs a 16-bit digital signal (resolution of 0.0078°C), greatly simplifying hardware design.
Why Choose the TMP117AIDRVR Over Traditional RTDs?
In traditional industrial designs, while PT100s are widely used, their drawbacks are evident: they require a precision constant-current source, a high-precision reference voltage, and complex linearization algorithms.
The TMP117 offers accuracy equivalent to a Class AA platinum RTD, yet consumes only a fraction of the power of traditional solutions. It features an integrated 48-bit EEPROM that not only stores calibration parameters but also serves as general-purpose non-volatile memory. This allows engineers to bypass cumbersome software lookup table algorithms and directly read temperature values accurate to two decimal places via I2C.
Application Scenarios
Thanks to its high accuracy and wide temperature range (-55°C to +150°C), the TMP117AIDRVR is widely used in:
Smart Wearables: Body temperature monitoring and skin temperature sensing;
Cold Chain Logistics: Real-time asset tracking for pharmaceuticals and food;
Automotive Electronics: Battery Management System (BMS) temperature monitoring and test equipment;
Industrial Instrumentation: Gas flow meters and heat meters;
Medical devices: Digital thermometers and patient monitors.
