• Question for your AD5258 digi-POT

    Dear Sir/Madam,

    I am just using your AD5258 digi-POT.
    So I found one trouble as following.
    Do you know why this trouble have happen?

    When the power supply to AD5258, the another device pull the SDA and SCL of AD5258 to LOW level. So AD5258 fix the output…

  • RE: AD5160 as resistance to eliminate clock reflection

    Hi Ian,

    AD5258 has a -3dB bandwidth of 18Mhz. This is the part with Maximum Bandwidth in our portfolio. This also will not be applicable for your application.

    您好！

    带宽达到10MHz的数字电位器产品，您可以看一下AD5258。

    Hi-

    I moved this question about the AD5258 to the Precision DACs Community.  Someone here should be able to assist you.

    1) Rw是否会随电源而改变？若是，能否提供显示该变化模式的图形？


    2) Rw是否会随编码不同而改变？若是，能否提供显示该变化模式的图形？


    3) 还有其它因素会导致Rw改变吗？


    4) AD5258的Rw典型值是多少？

  • Comment on AD9850 questions

    A design of mine also requires precise amplitude control.

    Current control on RSet via a ccs is one option, however is there any reason a  digipot such as the ad5258 (1K to 10K resistance range) is not a good solution? 

    Are there any implementation details I should…

    Hi Ian,

    Apologies for the delayed response to this question, it slipped through the net somehow.

    In answer to your questions:

    a) A digipot may be the best solution here. There's a selection of digipots available at the link below. The slew pin resistor…

  • RE: Maximum digital potentiometer frequency

    It depends. Bandwidth is a function of the code and end-to-end resistance RAB. Lower RAB and codes yield higher bandwidth.

    10MHz bandwidth or above is possible  if you use a 1 kΩ version of AD8400, AD5273 and limit your codes to a  low value range or using…

  • digi-POT_Bandwidth

    Q 

    I checked out several  of our Digi-Potentiometer, the bandwidth are all smaller
    than 1MHz.
    Would you please tell me whether we have Digital Potentiometer Products where
    bandwidth can be 10 MHz?

    Of course, the BW in the digipot are…
