**ADT7422CCPZ-RL7: A High-Accuracy, 16-Bit Digital I²C Temperature Sensor**

The **ADT7422CCPZ-RL7** is a high-precision digital temperature sensor from Analog Devices, designed to deliver exceptional accuracy and reliability for a wide range of applications. This 16-bit sensor provides industry-leading performance, making it an ideal choice for systems where precise thermal management is critical.

One of the most notable features of the ADT7422 is its **high accuracy of ±0.25°C** from 10°C to 65°C. This level of precision ensures that temperature readings are consistently reliable, which is essential in applications such as medical diagnostics, industrial process control, and high-performance computing. The sensor achieves this through its **internal 16-bit ADC**, which enables a temperature resolution of 0.0078°C per Least Significant Bit (LSB), allowing it to detect the smallest changes in temperature.

The device communicates via the **I²C-compatible digital interface**, which simplifies integration with microcontrollers and other digital systems. This interface supports standard (100 kHz) and fast (400 kHz) mode operations, providing flexibility for various design requirements. The ADT7422 also includes multiple user-programmable features, such as **setpoint and critical temperature alarms**, which can be configured to trigger interrupts when temperature thresholds are exceeded. This functionality is particularly useful for implementing overtemperature protection in electronic systems.

Housed in a compact **4 mm × 4 mm LFCSP (Lead Frame Chip Scale Package)**, the ADT7422 is suitable for space-constrained applications. Its low power consumption, typically 210 μA during normal operation and 2.1 μA in shutdown mode, makes it an excellent choice for battery-powered devices. Additionally, the sensor operates over a wide supply voltage range of 2.7 V to 5.5 V, enhancing its versatility across different platforms.

The **ADT7422CCPZ-RL7** is designed for robustness and ease of use. It requires no calibration or external components, reducing both design complexity and Bill of Materials (BOM) cost. Its high noise immunity ensures stable performance even in electrically noisy environments.

**ICGOODFIND**: The ADT7422CCPZ-RL7 stands out as a top-tier solution for high-accuracy temperature sensing, combining precision, integration ease, and low power consumption in a miniature package.
