AD8335是一款四通道可變?cè)鲆娣糯笃?VGA)，內(nèi)置低噪聲前置放大器，適合對(duì)成本和功耗敏感的應(yīng)用。每個(gè)通道均提供48 dB增益范圍、完全差分信號(hào)通道、有源輸入前置放大器匹配以及用戶可選的最大增益46 dB和38 dB，并且每個(gè)通道均具有單獨(dú)的增益控制。\n\n 前置放大器(PrA)具有×8 (18.06 dB)單端至差分增益，接受不大于625 mV峰峰值的輸入信號(hào)。在最大增益時(shí)，前置放大器噪聲為1.2 nV/√Hz，前置放大器與VGA合并折合到輸入端電壓噪聲為1.3 nV/√Hz。\n\n 假設(shè)噪聲帶寬(NBW)為20 MHz，奈奎斯特頻率為40 MHz，則輸入信噪比(SNR)為92 dB。引腳HLxx利用1 V 峰峰值或2 V 峰峰值滿量程(FS)輸入，優(yōu)化10位和12位ADC的輸出信噪比。\n\n 通道1和通道2通過(guò)引腳EN12啟用，通道3和通道4通過(guò)引腳EN34啟用。對(duì)于只需要VGA的應(yīng)用，可以將前置放大器關(guān)斷，從而顯著降低功耗。\n\n AD8335采用64引腳架構(gòu)芯片級(jí)封裝(9 mm × 9 mm)，額定溫度范圍為?40°C至+85°C工業(yè)溫度范圍。\n\n
