描述：HCPL-7840-500E
HCPL-7840-500E隔離放大器系列的設計用于電動馬達驅動器中的電流檢測。在一個典型的實施時，電機電流流經外部電阻，由此產生的模擬壓降由HCPL-7840-500E。差分輸出電壓在HCPL-7840-500E光學隔離柵的另一側。該差分輸出電壓與輸出電壓成正比。電機電流，可以轉換為單端如推薦的那樣使用運算放大器來發出信號應用電路。由于共模電壓擺幅數十納秒內幾百伏在現代開關變頻電機驅動器中很常見，HCPL-7840-500E旨在忽略非常高的共模瞬態壓擺率（至少10 kV /μs）。
HCPL-7840-500E隔離器的高CMR能力放大器提供了所需的精度和穩定性準確監控高噪聲電動機中的電動機電流控制環境，提供更順暢的控制各種類型的電機控制中（“轉矩波動”較小）應用程序。該產品還可以用于通用模擬信號需要高精度，穩定性，和線性在同樣嚴重的噪聲條件下。對于一般應用，我們推薦HCPL-7840-500E（獲得公差為±5％）。HCPL-7840-500E利用sigma delta（∑-Δ）模數轉換器技術，斬波器穩定的放大器和全差分電路拓撲采用Avago的0.8μmCMOS IC工藝制造。這些功能一起提供無與倫比的隔離模式噪聲抑制，以及出色的偏移和增益隨時間和溫度的精度和穩定性。這個性能以緊湊，可自動插入，行業標準的8引腳DIP封裝，可滿足全球范圍的要求監管安全標準。 （鷗翼面安裝選項＃300也可用）。
