Hi Team,

My customer needs to sense a triangle waveform current, the maximum frequency is about ~5MHz, the average current is about 10A, peak to peak is about 2~3A. The max common mode voltage is up to 6~7V.

Do you have any suggested amplifier? Thanks.

Let me know if you need more information.

Regards,

Nathan

Hi Nathan,

If the requirement is to sense the triangular waveform, instead of its average, we currently don’t have a product in the current sense amplifier portfolio that can support.

However you may be able to construct a discrete solution. Please create a separate thread once you zoom in on some potential candidate amplifiers, so that experts in corresponding product area can assist you further.

Regards, Guang

Hi Guang,

Thanks, could you please give me some ideas about what is the separate solution be like? Thanks.

Hi Nathan,

For the most part, an analog current sense amplifier resembles a diff amp. You are welcome to browse this e-book, which is a collection of app notes. There are many block diagrams which should be helpful in constructing a discrete solution that is tailored to your needs.
