• AD8122/AD8120 running hot

    Looking at the data sheets for the quiescent current, it would appear that, even when idle, the AD8122 is dissipating about 1W while the AD8120 dissipates between 0.4W and 1.2W.

    They glow quite brightly under the FLIR.

    Is this normal?

  • AD8120 Register Read/Write sequence

    Another question on the AD8120.

    Can the I2C registers be read/written sequentially (i.e., Address auto-increment, as in asking for the first register by memory address and have sequential reads/writes directly access the next sequential register)? Of…

  • AD8120可用于改善VGA线模糊抖动么

    现有计算机显卡输出VGA线较长(3米),为了改善信号质量,想设计单片8120线路(无8122),通过电位器调节达到预期效果,可否?

    一般AD810只能配合8122使用么?

    VGA的地怎么处理能更好的避免干扰?

    另外,AD8120的固定增益为2,那么输出VGA信号需要再衰减1/2才可以么?

    谢谢
