Dual-Channel Ultralow Noise Amplifier with Selectable Gain and Input Impedance

GENERAL DESCRIPTION The AD8432 is a dual-channel, low power, ultralow noise amplifier with selectable gain and active impedance matching. Each channel has a single-ended input, differential output, and integrated input clamps. By pin strapping the gain setting pins, four accurate gains of G = 12.

雙通道超低噪聲放大器，提供可選增益和輸入阻抗

AD8432是一款雙通道、低功耗、超低噪聲放大器，集成可選增益和有源阻抗匹配。每通道均有單端輸入、差分輸出和集成輸入箝位。通過綁定增益設(shè)置引腳，可實(shí)現(xiàn)的4個(gè)精確增益為12.04 dB、18.06 dB、21.58 dB和24.08 dB（分別對(duì)應(yīng)×4、×8、×12和×16）。當(dāng)G = 12.04 dB時(shí)的200 MHz帶寬使得該放大器非常適合許多高速應(yīng)用。\n\n AD8432的有源阻抗匹配造就了它出色的噪聲性能。放大器的輸入阻抗可以利用一個(gè)反饋網(wǎng)絡(luò)來調(diào)節(jié)，以便與信號(hào)源阻抗相匹配，且不影響噪聲性能。該器件的阻抗匹配和低噪聲特性可讓設(shè)計(jì)人員構(gòu)建能檢測(cè)極微弱信號(hào)、動(dòng)態(tài)范圍更寬的系統(tǒng)。\n ? 低噪聲\n輸入電壓噪聲= 0.85nV/√Hz\n電流噪聲 = 2.0 pA/√Hz\n\n? 高速\n帶寬：200 MHz (G = 12.04 dB)\n壓擺率：295 V/μs\n\n? 可選增益：\nG = 12.04 dB (×4)\nG = 18.06 dB (×8)\nG = 21.58 dB (×12)\n\n? 有源輸入阻抗匹配\n\n? 集成輸入箝位二極管\n\n? 單端輸入，差分輸出\n\n? 電源電壓范圍：4.5 V至5.5 V\n\n? 低功耗：每通道60 mW;
