AD603是一款低噪聲、電壓控制型放大器，用于射頻(RF)和中頻(IF)自動(dòng)增益控制(AGC)系統(tǒng)。它提供精確的引腳可選增益，90 MHz帶寬時(shí)增益范圍為?11 dB至+31 dB，9 MHz帶寬時(shí)增益范圍為+9 dB至+51 dB。用一個(gè)外部電阻便可獲得任何中間增益范圍。折合到輸入的噪聲譜密度僅為1.3 nV/√Hz，采用推薦的±5 V電源時(shí)功耗為125 mW。 \n\n 增益以dB為線(xiàn)性，經(jīng)過(guò)精密校準(zhǔn)，而且不隨溫度和電源電壓而變化。增益由高阻抗(50 MΩ)、低偏置(200 nA)差分輸入控制；比例因子為25 mV/dB，因此僅需要1 V的增益控制電壓就能覆蓋增益范圍的中間40 ? 線(xiàn)性dB增益控制 \n\n? 引腳可編程增益范圍\n?11 dB至+31 dB(90 MHz帶寬) \n9 dB至51 dB(9 MHz帶寬)\n\n? 所有中間范圍(例如?1 dB至+41 dB，帶寬：30 MHz)\n\n? 帶寬與可變?cè)鲆鏌o(wú)關(guān)\n\n? 輸入噪聲譜密度：1.3 nV/√Hz\n\n? 增益精度：±0.5 dB(典型值);
