OPA4277: opa4277

I have only one CT, and I want to deliver the signal to 4 DSP at the same time.

Can I use OP amp to do that? How to assure 4 DSP get the same and correct information?

    Hi Dragon,

    It's definitely possible to use an op amp to buffer a signal to drive multiple loads, however the choice of op amp will depend on the specifications you're trying to achieve. At a minimum, we'd need the following information to fully answer this:

    1. What is the output from the CT?
    2. What bandwidth do you need?
    3. What DSP/ADC model are you using, and at what sample rate?
    4. What sort of resolution are you trying to achieve?
    5. Are there any additional constraints for this application (e.g. power, supply voltage, package size/board area, cost)?
