ADE7768

內(nèi)置振蕩器僅累積正功率單相電能計(jì)量IC; ? Exceeds IEC61036/60687\n? Less than 0.1% Active Energy Error Over Dynamic Range of 500:1\n? Active Energy Measurement\n? High Frequency Pulse Output\n? Current sensor interface for current transformers or shunts\n? On-chip Temperature Sensor and Voltage Reference (2.5 V)\n? Low Power (20 mW typical)\n? Reverse Power Indication (REVP)\n\n;

ADE7768是一款精確電能計(jì)量IC。它是一種ADE7755的節(jié)省引腳版本，它內(nèi)置一個(gè)提高性能的精密振蕩器用作IC的內(nèi)部時(shí)鐘。ADE7768無(wú)需外部晶振或振蕩器，從而降低了用該芯片制造電能表的總成本。該芯片可直接連接分流電阻器。 ????????\n\n ADE7768可提供基于輸電線電壓和電流計(jì)算的瞬時(shí)有功功率和平均有功功率，并且僅累積正功率 - 忽略負(fù)功率。該器件規(guī)范超過(guò)IEC61036標(biāo)準(zhǔn)規(guī)定的精度要求。ADE7768中使用的模擬電路是ADC和參考電壓電路。所有其它信號(hào)處理（例如乘法和濾波）都是在數(shù)字域?qū)崿F(xiàn)的。這種信號(hào)處理方法可在隨環(huán)境條件和時(shí)間變化的很大范圍內(nèi)提供優(yōu)異的穩(wěn)定性和精度。\n\n 該芯片允許很小的滿度模擬輸入信號(hào)直接連接小阻值分流電阻器，從而不損失動(dòng)態(tài)范圍。ADE7768采用16引腳SOIC窄體封裝。\n\n AN-679應(yīng)用筆記可用作IEC61036標(biāo)準(zhǔn)描述的低成本、瓦時(shí)電能表參考設(shè)計(jì)的基礎(chǔ)。\n\n 注：欲設(shè)計(jì)三相電能表，推薦選用ADE7752。\n\n
