雙通道、超低噪聲可變增益放大器

AD604是一款超低噪聲、精度極高、雙通道、線性dB可變增益放大器(VGA)，針對超聲應(yīng)用中基于時間的可變增益控制進行了優(yōu)化，但同樣支持任何要求低噪聲、寬帶寬、可變增益控制的應(yīng)用。AD604的每個通道均提供300 k?輸入電阻和單極性增益控制，使用方便。用戶自定義的增益范圍、增益調(diào)整比例(dB/V)和輸出直流電平轉(zhuǎn)換則使性能進一步得到優(yōu)化。\n\n AD604的每個通道均采用高性能前置放大器，折合到輸入端的噪聲電壓為0.8 nV/√Hz。借助差分輸入指數(shù)放大器(DSX-AMP)架構(gòu)，AD604可實現(xiàn)精度極高的線性dB響應(yīng)。每個DSX-AMP均內(nèi)置6.908 dB至48.36 dB可變 ? 最大增益時具有超低輸入噪聲： \n0.80 nV/√Hz，3.0 pA/√Hz\n\n? 兩個獨立的線性dB通道\n\n? 每通道可編程絕對增益范圍：\n0 dB 至 48 dB (前置放大器增益 = 14 dB) \n到6 dB 至 54 dB(前置放大器增益= 20 dB) \n\n? 增益精度：±1.0 dB\n\n? -3 dB帶寬：40 MHz\n\n? 300 kΩ輸入電阻\n\n? 可變增益調(diào)整比例：20 dB/V至40 dB/V\n\n? 增益不隨溫度和電源變化而變化\n\n? 單端單極性增益控制\n\n? 在增益控制下限時電源關(guān)斷\n\n? 直接驅(qū)動ADC;
