Data Acquisition – Analog to Digital Converters (ADC) technology is crucial in many modern applications, particularly in the field of automation and control systems. The AD7714ARSZ-5REEL analog-to-digital converter (ADC) is one of the most popular products in this field and is used by engineers, designers, and technologists working in many businesses. In this article, we will discuss the application field, working principle, and features of the AD7714ARSZ-5REEL to provide a better understanding of this device and its applications.

Application Field

The AD7714ARSZ-5REEL is a precision ADC designed for use in high-end, precision system applications. This device is designed for integration in environments where low power is critical for system operation; it is ideally suited for applications such as the measurement of strain and temperature in industrial process control systems. Other potential applications include data acquisition systems and process control applications requiring precision, low-power performance and minimum system components.

Working Principle

The AD7714ARSZ-5REEL is a dual-channel, low-power, 24-bit ADC that supports both single-ended and differential analog inputs. The device converts analog inputs into digital words with 24-bit converter resolution and up to 16-bit data output for both channels. The AD7714ARSZ-5REEL employs an off-line delta-sigma (Δ–Σ) modulator architecture, which leverages oversampling techniques to achieve low noise performance. The Δ–Σ modulator consists of a filter, an analog-to-digital converter, and a digital-to-analog converter, as well as digital logic. This architecture is capable of excellent noise performance and fast, low-power operation.

Features

The AD7714ARSZ-5REEL has numerous features that make it attractive to engineers and designers:

• Differential input stage architecture ensures precise measurements in the presence of high-frequency noise
• On-board digital filter with adjustable cut-off frequency and adjustable order
• Programmable gain amplifier (PGA) for optimized input performance over a dynamic range of ±25 V
• Low power consumption, typically 10 mW in 24-bit operation
• Very low noise performance, as low as 500 nV/√Hz

The AD7714ARSZ-5REEL also incorporates numerous safety features, such as overvoltage protection, power-on reset, and a watchdog timer. This device is designed for system stability, with the ability to operate smoothly in dynamic temperature environments and very low power consumption for extended battery life. The AD7714ARSZ-5REEL also offers a small footprint, making it ideal for embedded applications.

Conclusion

In summary, the AD7714ARSZ-5REEL is a precision analog-to-digital converter with several features and advantages that make it well suited for use in high-end, precision system applications. It offers excellent noise performance, low power consumption, and safety features for system stability. This device can be easily integrated into existing systems for process control, data acquisition, and other applications requiring precision, low-power performance and minimum system components.
