    Hello everyone:

    Please see the attached file. This is a inverting and noninverting amplifer. The magnification is 14. I used the AD8044 for voltage amplify. When input frequency up to 200KHZ, The output amplitude became to decline, I need a DC to 1MHZ amplifer which can remain the same magnification and not to
    decline. How do I calculate the Gain Bandwidth and Slew Rate to choose a suitable OPA? or any part number meet the require.

    Many Thanks
