Dual Universal Switched-Capacitor Filters

General Description The MAX7490/MAX7491 consist of two identical low power, low-voltage, wide dynamic range, rail-to-rail, 2nd-order switched-capacitor building blocks. Each of the two filter sections, together with two to four external resistors, can generate all standard 2nd-order functions: ba

雙路、通用開關(guān)電容濾波器

MAX7490/MAX7491由兩個相同的低功耗、低電壓、寬動態(tài)范圍、軌到軌、二階開關(guān)電容構(gòu)建模塊組成。兩個濾波器部分各自都可以與兩到四個外部電阻一起生成所有標準二階函數(shù)：帶通、低通、高通和陷波（帶阻）。其中三個函數(shù)可同時使用。通過級聯(lián)兩個二階濾波器部分可以組成四階濾波器。同樣，通過級聯(lián)多個MAX7490/MAX7491可以輕松組成更高階濾波器。\n\n 提供兩種時鐘選項：內(nèi)置時鐘（通過使用外部電容實現(xiàn)），或者外部時鐘（用于實現(xiàn)更嚴格的截止頻率控制）。時鐘與中心頻率比為100:1。采樣以兩倍時鐘頻率進行，可將截止頻率和奈奎斯特頻率進一步分離。\n\n MAX7490/MAX ? 采用16引腳QSOP封裝的雙通道二階濾波器\n\n? 高精度\n?
