超低失真、超低噪聲運算放大器

AD797是一款極低噪聲、低失真運算放大器，非常適合用作前置放大器。它在音頻帶寬上具有低噪聲(0.9 nV(root)Hz)和低總諧波失真(-120 dB)特性，能夠達(dá)到麥克風(fēng)和調(diào)音臺中對前置放大器的較寬動態(tài)范圍要求。\n\n 此外還具有出色的壓擺率(20 V/μs)和增益帶寬(110 MHz)，因而非常適合低頻超聲應(yīng)用。\n\nAD797也適合要求極寬動態(tài)范圍的IR和聲納成像應(yīng)用。低失真和16位建立時間特性，使之非常適合緩沖Σ-Δ型ADC的輸入或高分辨率DAC輸出，特別是在地震監(jiān)測和頻譜分析儀等關(guān)鍵應(yīng)用中。輸出電流驅(qū)動為50 mA，額定電源電壓范圍為±5 V至±15 V，這些重要特 ? 低噪聲:\n輸入電壓噪聲(1 kHz)：0.9 nV/√Hz（典型值），\n1.2 nV/√Hz（最大值）\n輸入電壓噪聲（0.1 Hz至10 Hz）：50 nV p-p \n\n? 低失真:\n總諧波失真：-120 dB (20 kHz)\n\n? 出色的直流精度\n輸入失調(diào)電壓：80 μV（最大值）\nVOS 漂移：1.0 μV/°C\n\n? 高輸出驅(qū)動電流：50 mA\n\n? 出色的交流特性\n16-bit建立時間：800 ns（10 V步進(jìn)）\n增益帶寬：110 MHz (G = 1000)\n帶寬：8 MHz (G = 10)\n全功率帶寬：280 kHz (20 V p-p;
