双通道、超低噪声可变增益放大器

AD604是一款超低噪声、精度极高、双通道、线性dB可变增益放大器(VGA)，针对超声应用中基于时间的可变增益控制进行了优化，但同样支持任何要求低噪声、宽带宽、可变增益控制的应用。AD604的每个通道均提供300 kΩ输入电阻和单极性增益控制，使用方便。用户自定义的增益范围、增益调整比例(dB/V)和输出直流电平转换则使性能进一步得到优化。\n\n AD604的每个通道均采用高性能前置放大器，折合到输入端的噪声电压为0.8 nV/√Hz。借助差分输入指数放大器(DSX-AMP)架构，AD604可实现精度极高的线性dB响应。每个DSX-AMP均内置6.908 dB至48.36 dB可变 • 最大增益时具有超低输入噪声： \n0.80 nV/√Hz，3.0 pA/√Hz\n\n• 两个独立的线性dB通道\n\n• 每通道可编程绝对增益范围：\n0 dB 至 48 dB (前置放大器增益 = 14 dB) \n到6 dB 至 54 dB(前置放大器增益= 20 dB) \n\n• 增益精度：±1.0 dB\n\n• -3 dB带宽：40 MHz\n\n• 300 kΩ输入电阻\n\n• 可变增益调整比例：20 dB/V至40 dB/V\n\n• 增益不随温度和电源变化而变化\n\n• 单端单极性增益控制\n\n• 在增益控制下限时电源关断\n\n• 直接驱动ADC;
