Temperature Sensors - Thermostats - Solid State is a category of sensing and monitoring solution to regulate temperature, and LM26CIM5-VHA is one of the best representatives for the field. Specifically, LM26CIM5-VHA is a high-accuracy digital temperature sensor, able to detect the temperature ranging from -55℃ to 125℃(-67℉ to 257℉) and then provide the temperature data in the form of digital 13-bit word. This sensor was released by National Semiconductor in eariler 2000s, which adds a variety of features such as low power consumption, flexibility, reliability and so on. Therefore, LM26CIM5-VHA is widely used either in industry or in consumer electronics that realizes temperature control or detection functions.

Certain operation principles are behind the function of LM26CIM5-VHA. Firstly, according to the datasheet, an onboard MOS transistor will switch to a linear region when the extreme temperature range is reached, endowing LM26CIM5-VHA with the ability of temperature sensing. As the temperature further approaches the threshold, the current through the transistor will become more and more larger, and then lead the voltage drop across it to become more and more higher. Comparing the voltage drop across the transistor with the reference voltage, the temperature data can be obtained accordingly.

Apart from the general power consumption, LM26CIM5-VHA also has low power consumption in standby status. Specifically, when the device is in standby status, the quiescent current will not exceed 1 µA, making it very suitable for the cases that long-term power supply is required. In the meantime, the SMBus technology is also adopted, allowing the stop address recognition and then realizing the easy connection to the data bus.

For application, LM26CIM5-VHA is able to detect temperature changes for a wide variety of the products, such as PCs, PDAs, storage systems, and so on. Also, it can be used in various instrumentation solutions such as thermocouples, cold junction compensation, temperature compensation, and so on. Along with the development of science and technology, the application field is further extended to the car electronics, regulating temperature for the corresponding system. Furthermore, LM26CIM5-VHA is also used in some industrial control products.

In conclusion, LM26CIM5-VHA is a great representative of Temperature Sensors - Thermostats - Solid State. With its reliable, powerful and energy-saving features, the device can provide accurate temperature data and therefore is widely used in various application fields, such as electronics, instrumentation and industrial control. This can verify this device\'s great performance.
