简介本文章提供指南,概述如何将输配电应用的系统级要求转换成ADI数据手册中提供的模数转换器(ADC)规格。这些指南描述了测量和保护设备对系统级性能的影响。本文章使用AD7779作为参考。但是,介绍的一般原则适用于ADI的所有ADC。系统级要求尽管系统级规格因应用而异,但是一些关键要求可运用至大部分应用,包括最大和最小标称工作电流(INOM)和精度规格。精度通常取决于测量或保
Introduction This article provides a guide that outlines how to translate system-level requirements for power distribution applications into analog-to-digital converter (ADC) specifications provided in the ADI datasheet. These guidelines describe the impact of measurement and protection equipment on system-level performance. This article uses the AD7779 as a reference. However, the general principles outlined apply to all ADCs in ADI. System-Level Requirements Although system-level specifications vary by application, some key requirements apply to most applications, including maximum and minimum nominal operating current (INOM) and accuracy specifications. The accuracy usually depends on the measurement or guarantee
