內(nèi)置超低噪聲前置放大器和可編程輸入阻抗(RIN)的雙通道VGA

AD8332是一款雙通道、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 各通道內(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19 dB，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48 dB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40 mV至1 V范圍內(nèi)的控制電壓，增益控制接 ? 超低噪聲前置放大器\n電壓噪聲 = 0.74 nV/√Hz\n電流噪聲 = 2.5 pA/√Hz \n\n? 3 dB帶寬： 100 MHz \n\n? 低功耗： 每通道145 mW \n\n? 寬增益范圍，內(nèi)置可編程后置放大器\n-4.5 dB至+43.5 dB\n+7.5 dB至+55.5 dB \n\n? 低輸出參考噪聲\n48 nV/√Hz典型值 \n\n? 有源輸入阻抗匹配\n\n? 針對10位/12位ADC優(yōu)化 \n\n? 可選的輸出箝位電平\n\n? 采用5 V單電源供電 \n\n? 采用引腳架構(gòu)芯片級封裝;
