ADI ADE51xx单相电表解决方案
ADI公司的ADE5166/ADE5169/ADE5566/ADE55691集成了电表模拟前端(AFE)和具有8052 MCU核,RTC和LCD驱动器以及外设的固定功能DSP解决方案.工作电压2.4V-3.7V,25度C时动态范围1000:1时的有功功率误差小于0.1%,无功功率误差小于0.5%,微处理器采用基于8052内核,8052兼容的指令集,单周期4MIps特性.本文介绍了ADE5166/ADE5169/ADE5566/ADE5569主要特性,方框图, ADE5566/ADE5569电表框图以及采用8052 MCU,RTC和LCD驱动器的单相电表评估板主要特性,电路图,材料清单和PCB布局图.
The ADE5166/ADE5169/ADE5566/ADE55691 integrate the Analog Devices, Inc., energy (ADE) metering IC analog front end and fixed function DSP solution with an enhanced 8052 MCU core, a full RTC, an LCD driver, and all the peripherals to make an electronic energy meter with an LCD display in a single part.
The ADE measurement core includes active, reactive, and apparent energy calculations, as well as voltage and current rms measurements. This information is accessible for energy billing by using the built-in energy scalars. Many power line supervisory features such as SAG, peak, and zero crossing are included in the energy measurement DSP to simplify energy meter design.
