Miniature Isolation Amplifiers 0.3 mV Input Offset Voltage

Description The ACPL-C78A/C780/C784 family of isolation amplifers is designed for current sensing in electronic motor drives. In a typical implementation, motor currents ?ow through an external resistor and the resulting analog voltage drop is sensed by the ACPL-C78A/C780/C784. A di?erential outp

微型隔離放大器

ACPL-C78A/C780/C784 隔離放大器系列是專為電子電機驅(qū)動器和汽車應用而設計的電流感應裝置。ACPL-C78A/C780/C784 可在實施典型驅(qū)動程序中檢測電機電流通過外部電阻所產(chǎn)生的模擬電壓降。在 ACPL-C78A/C780/C784 光隔離屏障的另一端產(chǎn)生差分輸出電壓。這種差分輸出電壓與電機電流成正比，可以通過應用電路圖例所示的運算放大器轉(zhuǎn)換成單端信號。由于現(xiàn)今的開關變頻電機驅(qū)動系統(tǒng)中普遍存在共模電壓在數(shù)十納秒內(nèi)出現(xiàn)幾百伏擺幅的情況，因此 ACPL-C78A/C780/C784 采用可承受（最少 10 kV/μs）的超高共模瞬態(tài)變化壓擺率的設計，即使在高噪聲的電機控制環(huán)境 ·VCM = 1000V 時達到 15kV/μs 共模抑制能力\n·緊湊的自動插入擴展型 SO-8 封裝\n·0.00025 V/V/°C 增益溫度漂移\n·0.3mV 輸入失調(diào)電壓\n·100kHz 帶寬\n·0.004% 非線性度\n·安全法規(guī)認證（申請中）：\no? ?UL 1577（5000 Vrms/分鐘。） \no? ?CSA;
