单电源、低功耗、精密FET输入四通道缓冲器

AD8244是一款精密、低功耗、FET输入、四通道、单位增益缓冲器，设计用于将极高的源阻抗与信号链的其余部分相隔离。 其最大偏置电流为2 pA，电流噪声接近于零，输入阻抗则为10 TΩ，因此即使源阻抗为MΩ级别，也几乎不产生任何误差。 \n\n 很多传统运算放大器都将电源引脚排列在同相输入引脚旁边。 保护走线必须从这些引脚之间穿过，以避免漏电流远大于FET输入运算放大器的偏置电流。在DIP乃至SOIC等大型封装内，保护走线可以在引脚间穿过；但是，很多现代应用不允许这些封装消耗过多的面积。 AD8244具有独特的引脚排列可以解决这个问题，它在物理上将高阻抗输入与低阻抗电源以及其它缓冲器 • 低功耗\n250 μA（每放大器的最大电源电流） \n\n• FET输入\n输入偏置电流：2 pA（最大值，25°C）\n极高的输入阻抗 \n\n• 低噪声\n电压噪声：13 nV/√Hz (1 kHz)\n电压噪声：0.4 μV p-p\n（0.1 Hz至10 Hz）\n电流噪声：0.8 fA/√Hz (1 kHz) \n\n• 高直流精度\n最大失调漂移：3 μV/°C\n（B级） \n\n• 带宽：3 MHz \n\n• 独特的引脚排列\n输入至电源引脚间无漏电流\n提供保护功能 \n\n• 轨到轨输出 \n\n• 单电源供电\n输入范围扩展至地 \n\n• 宽电源范围\n单电源： ;
