ADC09QJ1300-Q1: 系统采样时,若除了Vdiff=0时值是稳定的,其它直流分量采出值会出现正弦波

Part Number: ADC09QJ1300-Q1

系统采样时,若除了Vdiff=0时值是稳定的,其它直流分量采出值会出现正弦波。通道2为0所以值的范围是127-129,其它三通道都有这个情况。

  • 您好,

    ADC09QJ1300-Q1的模拟输入要求共模电压在1.1V,变动范围是1.05V~1.15V:

    您描述说“其它直流分量采出值会出现正弦波。”,具体输入是什么?共模电压在1.1V吗?测量直流电压的话,只能测量1.05V~1.15V这个范围内的,超出此范围将不满足输入共模电压要求。
