Is there feedback for this?

Hi Fabian,

There is typical SR spec in DS already:

What is the bandwidth required for?

How are they planning on using that information?

What is the application and who is the customer?

The amplifier is used for current sampling in H bridge motor.

They want to get this information to calculate the limitation of frequency. Could you share this information?

Hi Fabio,

I need to check internally if we have such data.
