您好！如果是按照Figure24的连接，那么输出与运放的Slew Rate有关。请您参考这里的描述：For fast settling, the slew rate of the op amp should not impede the settling time of the DAC. Output impedance of the DAC is constant and code-independent, but to minimize gain errors, the input impedance of the output amplifier should be as high as possible. The amplifier should also have a 3 dB bandwidth of 1 MHz or greater. 您可以把您的威廉希尔官方网站
