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(kāi)關(guān)電容濾波器

MAX7490/MAX7491由兩個(gè)相同的低功耗、低電壓、寬動(dòng)態(tài)范圍、軌到軌、二階開(kāi)關(guān)電容構(gòu)建模塊組成。兩個(gè)濾波器部分各自都可以與兩到四個(gè)外部電阻一起生成所有標(biāo)準(zhǔn)二階函數(shù)：帶通、低通、高通和陷波（帶阻）。其中三個(gè)函數(shù)可同時(shí)使用。通過(guò)級(jí)聯(lián)兩個(gè)二階濾波器部分可以組成四階濾波器。同樣，通過(guò)級(jí)聯(lián)多個(gè)MAX7490/MAX7491可以輕松組成更高階濾波器。\n\n 提供兩種時(shí)鐘選項(xiàng)：內(nèi)置時(shí)鐘（通過(guò)使用外部電容實(shí)現(xiàn)），或者外部時(shí)鐘（用于實(shí)現(xiàn)更嚴(yán)格的截止頻率控制）。時(shí)鐘與中心頻率比為100:1。采樣以兩倍時(shí)鐘頻率進(jìn)行，可將截止頻率和奈奎斯特頻率進(jìn)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?
