DRV5055-Q1: slew rate limitations?

Hello Yivgeni,

That's not something we specify in our datasheet.  I need to reach out to our design team to see if they can provide any insight on what it might be.  I will try to give you an update tomorrow.

Ok thanks.

Its really important from my end because I has to sense current that it change rate isn't small.

Hello Yivgeni,

Unfortunately slew rate is not something we provide at this point in time.  TI does have devices specifically designed for current sensing, perhaps someone from their team can help you out. Can you provide a little more detail on what you are trying to accomplish?  With that information we might be able to direct you to a device that has slew rate specified and meets your other criteria.

OK.

Let me ask it in other way. can I measure sine wave flux density with amplitude of 0.16 [T] and frequency of 1kHz without attenuation, distortion or phase lag? 

You said the bandwidth is 20kHz, but I assume it is for small signal excitation.

Would much appreciate a detialed answer.

Thanks.

Hello Yivgeni,

We presently do not have the capability to test how our device would respond to that strength of signal at that frequency.  Im still investigating test workarounds for that, but I do not think I will be able to give a good answer on that anytime soon.
