It is designed for industrial applications and has been adopted for applications such as automotive, health, aerospace, and consumer electronics.Features
The DS28EA00U+ temperature sensor features an analog-to-digital converter (ADC), which enables digital output transmission using either a pulse-width modulation (PWM) or UART interface. The device features a 400ppm/K resolution, providing accurate temperature control in a variety of applications. Additionally, the device features a wide input range of -40 to +125°C, allowing for more control over temperatures in extreme temperatures. A low power consumption feature saves energy and provides a more reliable solution than similar devices offering the same functionality.In addition to the high resolution and low power features, the DS28EA00U+ also offers a variety of other features, such as high slew rate for fast temperature measurement, a wide power supply range, an adjustable PWM frequency, and an offer to customize sensor behavior through the pre-programmed coefficients. Application Field
The DS28EA00U+ can be used in a wide variety of applications that require accurate temperature measurement and control. For example, it can be used in automotive applications to measure and monitor engine temperatures as well as in heating/cooling systems in buildings. Additionally, it can be used for critical temperature monitoring in cell phone batteries and a variety of other applications.The device is also suitable for industrial applications such as process control, stress testing, and other process-critical applications. Additionally, it can be used for medical and health-related applications, including patient monitoring, thermography, and other temperature-sensitive medical diagnostics.Working Principle
The DS28EA00U+ is based on the thermistor principle of temperature measurement. The device features a built-in thermistor, which is a temperature-dependent resistor that changes its resistance as the temperature changes. When a voltage is applied across the device, the resistance between the two terminals changes according to the temperature.By measuring the change in resistance between the two terminals, a temperature measurement can be taken, even when there is no physical connection. This is implemented in the DS28EA00U+ through the use of the patented SmartBridge technology, which is able to measure the voltage across the device, convert it to a temperature measurement, and transmit it digitally over a network.Conclusion
The DS28EA00U+ is a highly accurate and reliable temperature sensor that is suitable for a wide range of temperature sensing applications. It features an integrated analog-to-digital converter, as well as a range of features such as high slew rate for fast temperature measurement, and adjustable PWM frequency. Additionally, its unique SmartBridge technology enables it to measure temperatures over a wide range without physically connecting to the device. As such, the DS28EA00U+ is the ideal choice for industrial, automotive, medical, and other temperature sensing applications.
