    Operation Amplifiers for high frequency application

    Ok, I learned some good things about Op Amps but I require : An Op Amp whose Output swing (Vp-p) is between 60 to 100 volts @ at 100 plus khz. Ideally it would be 60 to 100 volts peak t peak at 200 khz. How can I search for this?

    Operation Amplifiers for high frequency application

    Thanks that is great. I will check the slew rate and the frequency of operation.

    Operation Amplifiers for high frequency application

    Sounds great! I need 60 - 100 p-p. Today, we managed to get 60 p-p using OPA445 (see above posts) because I changed the power supply to have +/- 31 volts. We were only limited by function generator amplitude to test it becausei t wouldn't go above 10 volts. The only thing though is that...

    Operation Amplifiers for high frequency application

    Thanks. but all this sound like I am not able to get 30-50 volts at 100-200 khz and only 15-20 volts. Is there anything else I should be looking at?

    Operation Amplifiers for high frequency application

    Thanks Carl, I really appreciate it. You are absolutely right. Just to make sure, by 50 volts you mean that I could use +30 & -20 volts since sometimes the power supplies have limits on negative and positive amount. Also, I have been reading from that Cookbook you mentioned and found out...

    Operation Amplifiers for high frequency application

    Thanks. I can already test with OPA454, and so far had configured it in a way to use 2 resistors R1 and R2, where R2/R1 = 2. Just trying to find out what the exact relationship between input and output will be. The schedmatic is a simple non-inverting configuration with one resistor (R1) between...

    Operation Amplifiers for high frequency application

    Hi Ddlgoff, Thanks for the links. Using the first link, I have not yet found which OP AMP can magnify the input voltage 3-5 times (this is the gain in units V/V). As for the 2nd link, while the knowledge might help get familiar with Op Amp and RF apps, I don't think it specifically helps my...

    Operation Amplifiers for high frequency application

    Hi, We would like to connect an amplifier to produce the appropriate alternative current for a high frequency actuating system. Who here knows where I can find an opamp with the following charachtristics: 1) Non-inverting 2) Amplifies an alternating input current 3 to 5 times 3) Works...
