Problem:
THS4021 is used in both inverting and non-inverting configuration. In non-inverting configuration, when the gain of opamp is such that the output is less than +/-15V, there are many ripples or noise when the pulse waveform or sine waveform at any frequency between 10Hz to 1 MHz is fed. When the variable resistance in feedback path is increased, the ripples decreases. In our application, We need a gain of 2.
Please suggest if any value of resistance or capacitance can be changed to improve the response.
Or there is any other one-to one replacement of the IC to meet the requirement.
Thanks.
