四通道、低噪聲、低成本可變增益放大器

AD8335是一款四通道可變增益放大器(VGA)，內置低噪聲前置放大器，適合對成本和功耗敏感的應用。每個通道均提供48 dB增益范圍、完全差分信號通道、有源輸入前置放大器匹配以及用戶可選的最大增益46 dB和38 dB，并且每個通道均具有單獨的增益控制。\n\n 前置放大器(PrA)具有×8 (18.06 dB)單端至差分增益，接受不大于625 mV峰峰值的輸入信號。在最大增益時，前置放大器噪聲為1.2 nV/√Hz，前置放大器與VGA合并折合到輸入端電壓噪聲為1.3 nV/√Hz。\n\n 假設噪聲帶寬(NBW)為20 MHz，奈奎斯特頻率為40 MHz，則輸入信噪比(S ? 低噪聲前置放大器(PrA)\n\n? 電壓噪聲 = 1.3 nV/√Hz(典型值)\n\n? 電流噪聲 = 2.4 pA/√Hz(典型值)\n\n?
