描述：ACPL-C87H-500E
Broadcom®ACPL-C87B / C87A /ACPL-C87H-500E電壓傳感器是專門為以下目的設計的光隔離放大器電壓感應。其2V輸入范圍和高1-GΩ輸入阻抗，使其非常適合隔離電壓感測電子功率轉換器應用中的要求，包括電機驅動器和可再生能源系統(tǒng)。在一個典型的電壓感應實現(xiàn)，電阻電壓分壓器用于縮放直流母線電壓以適合輸入電壓傳感器的范圍。差分輸出電壓與輸入電壓成正比隔離層的側面。對于一般應用，ACPL-C87A（±1％增益公差）和ACPL-C870（±3％增益公差）為推薦的。對于高精度要求，可以使用ACPL-C87B（增益公差為±0.5％）。的
ACPL-C87B / C87A /ACPL-C87H-500E系列采用5V單電壓工作并提供出色的線性度。高電平有效提供停機引腳，可將IDD1電流降低至僅15A，使其適合電池供電和其他對功耗敏感的應用。高共模瞬變抗擾度（15 kV / ms）
ACPL-C87B / C87A /ACPL-C87H-500E提供了精確度和準確監(jiān)控直流母線電壓所需的穩(wěn)定性高噪聲環(huán)境。結合卓越的光學耦合技術ACPL-C87B / C87A /ACPL-C87H-500E實現(xiàn)sigma-delta（Σ-Δ）調制，斬波器穩(wěn)定的放大器和差分輸出以提供無與倫比的隔離模式噪聲抑制，低失調，高獲得準確性和穩(wěn)定性。該性能在緊湊，可自動插入的Stretched SO-8（SSO-8）符合全球法規(guī)安全標準的包裝。
