您好,现在在用ADS1298做产品,可以单电源3.3V供电吗?双电源对比单电源有什么优势?我现在想电池电压抬升单电源3.3V供电可以吗?

  • 您好,

    可以单电源3.3V供电,只要供电电压在ADS1298 datasheet推荐的工作范围内都可以,见datasheet 7.3 Recommended Operating Conditions表格。
    双电源、单电源供电区别主要在于输入信号范围不一样:INP和INN的绝对范围必须介于AVSS– 0.3V和AVDD+ 0.3V之间,以及输入共模电压范围,见datasheet 9.3.1.5.1 Input Common-Mode Range部分。
