ADS8638使用

Other Parts Discussed in Thread: ADS8638

ADS8638可以采用12V单电源供电吗?可以单电源信号进行负压采集吗?

  •  您好,ADS8368的供电电压范围如下,您指的单电源供电, 那就是HVSS也接地是吗?HVSS最大可以接0V,但是输入信号的电压范围为HVSS~HVDD, 所以如果HVSS也接地的话,输入信号就不能负压,所以就不能对负压进行采集。

  • 您好,
    HVSS和HVDD需要使用双极性电压供电,供电范围请查看数据手册电气特性表格POWER-SUPPLY REQUIREMENTS处。输入信号范围可为±10V, ±5V, ±2.5V, 0V to 5V, and 0V to 10V,可通过寄存器设置选择
