It is especially suitable for applications where the temperature range is wide, such as in furnace control. It is also widely used in automotive, aerospace and biomedical applications where accuracy and reliability of the temperature measurement are critical.

Mechanical Specifications

The ADT7408CCPZ-REEL is available in a 5x5mm QFN package. It requires a supply voltage of 3.5V to 7V and has an operating temperature range of -40°C to +125°C. It can measure temperatures up to +150°C with an accuracy of ±1°C and a resolution of 0.0625°C.

Working Principle

The ADT7408CCPZ-REEL temperature sensor is based on a thermistor, which is a variable resistor whose resistance changes with changes in temperature. The thermistor is connected to an amplifier and comparator circuit, which converts the resistance changes into either an analog or digital output. The analog output of the ADT7408CCPZ-REEL is an voltage ranging from 0V to VCC, with VCC being the selected supply voltage. The digital output of the ADT7408CCPZ-REEL is an open-drain signal that can be interfaced to any logic circuit.

Alert Signals

The ADT7408CCPZ-REEL can be programmed to generate an alert signal when the temperature exceeds a certain preset limit. The alert signal is an open-drain signal that can be used to activate an alarm or take other safety measures.

Conclusion

The ADT7408CCPZ-REEL temperature sensor provides both analog and digital outputs, making it suitable for a variety of temperature sensing applications. Its accuracy and reliability make it suitable for a wide range of applications, from automotive to aerospace. It is available in a compact 5x5mm QFN package, making it easy to integrate into designs.
