Temperature sensors are electronic devices designed to detect, measure and respond to changes in temperature. They are used widely in industrial and commercial applications, as well as in consumer electronics, to measure the temperature of air, liquids, or any other fluids. Temperature sensors come in two basic varieties: analog and digital output. Among the most popular analog output temperature sensors is the ADT75ARZ-REEL.

The ADT75ARZ-REEL is a precision digital temperature sensor. It is intended to accurately measure temperatures within a range of -75℃ to +150℃. The device features a temperature range of -40 to +125C with a resolution of 0.0625℃/LSB. It has an accuracy of ±1℃ from 0.1℃ to 70℃, or ±2℃ in the full temperature range. Other features of the ADT75ARZ-REEL include its low power consumption, small package size, and a variety of interface options for connecting to an external controller.

Application Field of ADT75ARZ-REEL

The key applications of the ADT75ARZ-REEL temperature sensor include smart phones, gaming consoles, HVAC systems, refrigerators, and medical equipment. It is also suited for a wide range of industrial and commercial temperature measurements, including industrial process control, environmental monitoring, and consumer electronics. Additionally, the ADT75ARZ-REEL has been designed to interface with microcontrollers such as the PIC, AVR, and ARM Cortex-M families.

Working Principle of ADT75ARZ-REEL

The ADT75ARZ-REEL works by using the characteristics of a thermistor to convert temperature into a variable resistance. The device has a voltage divider, consisting of a thermistor and a reference resistor. When the temperature increases, the resistance of the thermistor increases, and the voltage at the output terminal changes. The device then converts this voltage into a digital signal, which is then output as a signal on the ADT75ARZ-REEL. The temperature can then be read from the ADT75ARZ-REEL by an appropriate controller.

The ADT75ARZ-REEL also features an internal 16-bit digital-to-analog convertor (DAC) with a 0.2 decibel (dB) linearity and a 0.8 µV/K drift. This allows it to convert the temperature signal into a voltage, current, or digital value. Additionally, the ADT75ARZ-REEL has an integrated temperature limit setting, which allows the temperature of the device to be set to an absolute upper or lower limit. This ensures that the device runs at a safe temperature range and prevents it from over-heating.

Overall, the ADT75ARZ-REEL is an ideal choice for temperature sensing applications where accuracy, precision, small size, and low power consumption are important. It is well-suited for industrial, commercial, and consumer temperature sensing applications, and can interface with many different microcontrollers.
