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

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…
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…
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…
