The DS1626U+ is an integrated direct-drive temperature sensor capable of measuring temperatures from -45°C to 135°C. With its small package it is ideal for use in environments where the utmost accuracy is necessary. The performance of this temperature sensor has been optimized and is extremely accurate over a wide range of temperatures, with low power consumption and high accuracy. This article will discuss the application fields and working principle of the DS1626U+.

Application Fields

The DS1626U+ is a highly accurate temperature sensor that can measure temperatures from -45°C to 135°C. It has a response time of 400 ms, making it suitable for use in thermophysical applications, such as thermoelectric conversion, automotive cooling systems, and home appliance temperature control. It is also used in medical equipment and in non-contact industrial temperature monitoring. In these applications, the DS1626U+ provides highly accurate temperature measurements with minimal power consumption.

Working Principle

The working principle of the DS1626U+ is based on the thermoelectric effect. This thermoelectric effect occurs when two dissimilar materials, such as a semiconductor and a conductor, are connected together. When a temperature difference is applied across the two connections, a voltage difference will be created between the two materials. This voltage difference can be measured and used to determine the temperature difference.

The DS1626U+ is designed with two thermistors connected to a differential amplifier. The thermistors are manufactured in a thin film and metal-oxide based process, which allows for precise temperature sensitive characteristics. The differential amplifier is designed with low power circuitry, allowing it to measure temperature with minimal power consumption. The measured voltage across the two thermistors is used to calculate the temperature with an accuracy of ±0.5°C.

The DS1626U+ also has an integrated temperature-to-digital array, which converts the measured temperatures into digital codes. These digital codes can then be interpreted by an external controller, such as a microcontroller or a digital signal processor. This allows the sensor to be used in applications that require a digital output.

Conclusion

The DS1626U+ is an extremely accurate and low-power temperature sensor capable of measuring temperatures from -45°C to 135°C with an accuracy of ±0.5°C. Its integrated temperature-to-digital array allows for a digital output, making it suitable for use in thermophysical applications, medical equipment, and non-contact industrial temperature monitoring. With its high accuracy and low power consumption, the DS1626U+ is a top choice for Temperature Sensors - Analog and Digital Output.
