• AD5144

    This is a +5V part. Basically it has 4 rheostats - that is the mode I am using. I understand that the voltage across the terminals {A and B}  OR {AW and B} cannot exceed 5V. Please confirm this.

    Secondly, if the rheostat is used in a circuit the max…

  • RE: AD5144 doesn't load configuration on power-up

    Hi,

    Would you also be able to provide the teminal voltages of the AD5144? You may want to look at the power up sequence section of the AD5144 on page 32 of the RevA. data sheet.

    Regards,

  • AD5144+LT3476使用问题

    AD5144+LT3476 搭配使用,发现LT3476的Vref只有0.8V,将两者断开后Vref=1.05V正常。AD5144的上电时序以及其他都已经符合SPEC要求,但是VREF接到AD5144的A端时还是会被拉到0.8V。请帮忙看看这是什么原因造成的。

  • RE: AD5144A+LT3476使用问题

    1. 在板子上断开Vref,上电量测Vref05V。上电后再将Vref 接接到AD5144A,这样可以保证AD5144上电的时序是正确的,接上后再量Vref0.8V
    2. 在板子上断开Vref,外部power supply 05VAD5144,上电后量测AD5144A1.05V,此时正常。
    3. 这样看来1.05V如果从外部给就是正常的(AD5144上电时序先不考虑),如果接LT3476Vref 1.05V就会变成0.8V

      两个IC分开来都是好的,接在一起就出问题。请帮忙看下
  • AD5144 Operation

    Hello,

    I received a couple of questions about AD5144 operation from our customer.  

    1) We can see following description in the datasheet of AD5144.

    After the SPI communication process has been accomplished, will it spend some time for AD5144 to switch to the new resistance value?

    Thanks.

    謝謝您的建議,目前決定使用AD5144來進行控制。

    AD5270的port數有點不足。
