TLV3801: Problems with the Output Coupling of the TLV3801

Part Number: TLV3801
Other Parts Discussed in Thread: LMH6401,

plan to use the LMH6401 to amplify the output signal from the TLV3801, yet its common-mode voltage goes beyond the LMH6401's input common-mode range. Which coupling schemes are available for this application?

  • 通常直接选择差分交流耦合(两路各串联一个隔直电容,阻断 TLV3801 的共模电压,让 LMH6401 输入自行偏置。)即可;
    如果信号可能长时间保持高或低电平,则应考虑有源电平转换。
