128通道数字X射线模拟前端

AD8488是一款128通道模拟前端，为高性能数字X射线系统而设计。它的模拟通道由一个积分器和增益可选的单端转低阻抗差分输出组成。该模拟通道将X射线或光电二极管检波器收集的电荷转换成电压信号。通道由CMOS晶体管组成，这些晶体管采用典型高输入阻抗的CMOS门。该设备的积分器采用一系列可选电容值，产生与电荷有关的电压，可适应广泛的输入电荷值。单端输入转差分输出电压放大器位于积分器之后，在这里偏移和低频噪声电压从输入电压中减去。一条128:1通道差分MUX位于缓冲器之后，驱动模拟输出缓冲。同时还提供开关驱动器和某些数字计时功能；这些功能全部集成在255引脚BGA基板上。全部128通道的电荷转换是同 • 128个积分通道 \n\n• 相关双采样纠错 (CDS)\n- 校正VOS和LF噪声\n\n• 功耗/通道\n- 正常值：11 mW\n- 低功耗：4 mW\n\n• 低输入漏电流\n- 1.5 pA（典型值）\n\n• 低折合到输入端噪声 (QNI)\n- 1000 e−rms（典型值）\n\n• 线性误差\n- 0.03%（典型值）\n\n• 紧凑型17 mm x 17 mm BGA封装 \n\n• 滤波器时间常数可选 \n\n• 4种可选输入电荷范围 \n\n• 10种可选增益范围;
