AD5560 MEASOUT OUTPUT

使用AD5560给DUT器件供电,并测量静态工作电流与动态工作电流时遇到问题,

当GAIN设置为MEASOUT 增益为0.2,MI增益为10或20时。MEASOUT range 仅 0.5~1V(中心值为0.74左右,不同芯片略有差异),且不能对电流范围内的电流值进行全范围测量。

当GAIN设置为MEASOUT 增益为1,MI增益为10或20时。MEASOUT range 仅±1V,(中心值为0左右,不同芯片略有差异)且不能对电流范围内的电流值进行全范围测量。

与AD5560的DATA Sheet中表9,表10不符。其余功能正常使用。

尝试调整offset reg 的reg code 来调整Vmin数值,并没有什么改变,硬件上Vref = 5V。请教可能存在什么其他问题导致该现象。谢谢

  • Hi ,

    I tried using google translate to understand your query. From there, it says that the AD5560 is being measured at rest. May I know more details about this specifically on what you meant by "at rest"? Additionally, I have other questions that needs answers from you so we could provide you a better support on this query of yours. First, what is the current range that you are using during the test and what are the voltages that you set? How are you measuring the output? Lastly, do you use our evaluation boards for this test? If you can provide actual data on your test, please let me know so I could have more insights on your tests. Thank you!
