The ADE7978ACPZ is an integrated circuit (IC) component designed for measuring and monitoring electrical parameters in energy measurement applications. Produced by Analog Devices, this highly accurate and versatile IC offers a wide range of features and functionalities.
One of the key features of the ADE7978ACPZ is its ability to measure various electrical parameters, including voltage, current, power, energy, and harmonic content. It achieves this by integrating a high-performance analog front end, a digital signal processing (DSP) engine, and a flexible digital interface.
The IC employs a sigma-delta analog-to-digital converter (ADC) with a resolution of up to 23 bits, ensuring precise measurements across a broad dynamic range. It also includes a highly stable on-chip voltage reference, minimizing the need for external components and calibration. The ADE7978ACPZ can measure both single-phase and three-phase systems, making it suitable for a wide range of applications.
Furthermore, the IC offers advanced energy monitoring features such as active, reactive, and apparent power measurements, as well as power factor and frequency calculations. It also supports integrated energy accumulation, allowing for accurate energy billing or data logging.
The ADE7978ACPZ integrates an onboard digital signal processing engine that enables real-time processing and calculation of various parameters. This eliminates the need for external microcontrollers or additional processing components, simplifying system design and reducing costs
