TI's high-precision digital temperature sensor is here. Will it really bring a different experience? [Copy link]

 

Texas Instruments (TI) recently launched a new temperature sensor series that can achieve up to ±0.1°C accuracy over a wide temperature range, helping to simplify system design for industrial and medical applications. The TMP117 is the first single-chip temperature sensor with similar performance to Platinum RTDs, while significantly reducing design complexity and power consumption. The TMP117M is a digital temperature sensor suitable for medical applications that meets the requirements of medical thermometers. These new devices can help engineers develop patient monitors, field transmitters and metering applications with high accuracy and ultra-low power consumption more quickly. It is said that this new temperature sensor series has the following features: 1. High accuracy without calibration The new sensor series can achieve up to ±0.1°C accuracy over a wide range, and achieve zero calibration during the manufacturing process, saving design time and reducing production costs for systems that require high accuracy. Meets Clinical Temperature Requirements: For medical applications, the TMP117M achieves ±0.1°C accuracy from 30°C to 45°C, meeting American Society for Testing and Materials (ASTM) E1112 and International Organization for Standardization (ISO) 80601 requirements for patient thermometers. Achieving Class AA RTD accuracy for industrial applications: The TMP117 provides direct reading of temperature without additional linearization or acquisition errors, maintaining accurate temperature over a wide range: o ±0.1°C from -20°C to +50°C o ±0.15°C from -40°C to +50°C o ±0.2°C from -40°C to +100°C o ±0.25°C from -55°C to +125°C o ±0.3°C from -55°C to +150°C 2. Minimize system and software complexity TI's new digital temperature sensors help engineers: Reduce system complexity: By using the TMP117, engineers can achieve the accuracy required for their applications without the design and manufacturing complexity of typical solutions. In contrast, to achieve a similar level of accuracy to that of a Platinum RTD, engineers must select a variety of precision components, simulate and fine-tune the circuit, carefully lay out the PCB to avoid impedance mismatches, and develop software for linearizing the output and calibrating each system. Accelerate design efficiency: The TMP117 and TMP117M are compatible with I2C and SMBus interfaces and provide direct digital readings of temperature, significantly reducing design, layout, and simulation time, and accelerating time to market. 3. Reduce power consumption by up to 95% With the TMP117 and TMP117M, which consume only 6.3μW of power, engineers can achieve longer battery life and more accurate temperature measurements in their designs. Significantly reduce power consumption: The TMP117 consumes 95% less power than a typical RTD measurement system, which enables designers to meet strict power budgets in field transmitters or battery-powered applications. Minimize self-heating effects: The low power consumption of the TMP117 and TMP117M minimizes the effects of self-heating, resulting in more accurate temperature measurements. According to the official introduction of this product from TI, it is a really good temperature sensor. Friends who use this product in new designs can give some suggestions and references to see if this new temperature sensor is really as described by the official. Reducing power consumption by up to 95% is really incredible. I don’t know if it is true. If it is true, it will really help the development of new products.

I just don’t know if it’s really that easy to use. I hope everyone will use it and share their thoughts.

Pretty good.

We have specially developed the first-line bus acquisition module LCT2662M and the instrument LCT2201C, which can collect the commonly used first-line bus devices ds18b20 and analog ds2438, etc. It supports 64 ds18b20 simultaneous acquisition. The output rs485 bus is convenient for communication with computers and other terminals, and is commonly used for grain warehouse granary temperature measurement, coal silo temperature measurement, water storage temperature measurement, etc.
