四通道、低噪声、低成本可变增益放大器

AD8335是一款四通道可变增益放大器(VGA)，内置低噪声前置放大器，适合对成本和功耗敏感的应用。每个通道均提供48 dB增益范围、完全差分信号通道、有源输入前置放大器匹配以及用户可选的最大增益46 dB和38 dB，并且每个通道均具有单独的增益控制。\n\n 前置放大器(PrA)具有×8 (18.06 dB)单端至差分增益，接受不大于625 mV峰峰值的输入信号。在最大增益时，前置放大器噪声为1.2 nV/√Hz，前置放大器与VGA合并折合到输入端电压噪声为1.3 nV/√Hz。\n\n 假设噪声带宽(NBW)为20 MHz，奈奎斯特频率为40 MHz，则输入信噪比(S • 低噪声前置放大器(PrA)\n\n• 电压噪声 = 1.3 nV/√Hz(典型值)\n\n• 电流噪声 = 2.4 pA/√Hz(典型值)\n\n• NF = 7 dB (RS = RIN = 50 Ω) \n\n• 单端输入：VIN 最大值 = 625 mV 峰峰值\n\n• 有源输入匹配\n\n• 输入信噪比(噪声带宽 = 20 MHz)= 92 dB\n\n• VGA\n差分输出\nVOUT最大值 = 5 V峰峰值，RL = 500 Ω差分\n增益范围(8 dB输出增益步进)\n低增益模式：−10 dB至+38 dB\n高增益模式：−2 dB至+46 dB\n精确线性dB增益控制\n;
