DS2423P+T&R

The DS2423P+T&R device is a drop-in replacement for the popular DS2423P device, with the additional benefit of having both temperature and resistance measurement capabilities. This device is a versatile, highly integrated, low-power solution ideal for applications where accurate temperature and resistance sensing are paramount. The DS2423P+T&R can be used in many applications in industrial, automotive and medical fields, such as monitoring safety conditions in a laboratory, measuring the ambient temperature in a vehicle, or measuring vital signs in a medical device.

The DS2423P+T&R integrates an advanced resistance-sensing element and a wide-temperature range thermistor, providing great flexibility and accuracy for both measurements. It also provides a convenient way to collect, store, and retrieve data from several locations. Furthermore, the device supports a wide operating temperature range from -40°C to 125°C, making it suitable for various industrial, automotive and medical applications.

The working principle of the DS2423P+T&R is relatively simple. The chip contains two separate measurement elements: one for detecting the resistance of a certain element or material, and one for detecting the temperature of a certain environment. When the power is applied to the device, the voltage across the sense resistor is measured by a precision low-power differential amplifier, providing a direct output of resistance. The temperature sensing element consists of a thermistor and an integrated temperature sensing element, which works in a similar way to measure the temperature over a wide range of -40°C to +125°C.

The DS2423P+T&R is an ideal solution for applications that require simultaneous measurements of both resistance and temperature. It provides a cost-effective way to implement these functions without the need for additional components and can be used in a wide variety of industrial, automotive and medical applications. With this device, designers can quickly and easily implement both resistance and temperature sensing capabilities in their products with minimal effort and cost.
