內(nèi)置超低噪聲前置放大器和可編程輸入阻抗(RIN)的單通道VGA

AD8331是一款單通道、超低噪聲、線性dB可變增益放大器(VGA)，針對超聲系統(tǒng)應(yīng)用進行了優(yōu)化，可以用作低噪聲可變增益元件，頻率最高為120 MHz。\n\n 這款器件內(nèi)置一個超低噪聲前置放大器(LNA)、一個48 dB增益范圍的X-AMP? VGA以及一個具有可調(diào)輸出限制功能的可選增益后置放大器。LNA增益為19dB，具有單端輸入和差分輸出。LNA輸入阻抗可以利用一個電阻來調(diào)節(jié)，以便與信號源相匹配，且不影響噪聲性能。\n\n VGA的48dB增益范圍使這些器件適合各種不同的應(yīng)用。帶寬在整個增益范圍內(nèi)可保持出色的一致性。對于40mV至1V范圍內(nèi)的控制電壓，增益控制接口可提 ? 超低噪聲前置放大器\n\n? 電壓噪聲 = 0.74 nV/√Hz\n\n? 電流噪聲 = 2.5 pA/√Hz\n\n\n\n\n? 3 dB帶寬：120 MHz\n\n? 低功耗：每通道125 mW\n\n? 可編程后置放大器提供寬增益范圍\n? LO增益模式：?4.5 dB至+43.5 dB\n\n? HI增益模式：7.5 dB至55.5 dB\n\n\n\n\n? 折合到輸出端的噪聲較低：48 nV/√Hz（典型值）\n\n? 有源輸入阻抗匹配;
