  • AD5724: Digi-POT_Bandwidth

    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 limited by…

  • 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.

  • AD5258_Rw

    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…
