According to the THS3217 data sheet, the output stage of the device shows overshoot for a step response. My customer has a circuit that shows similar and they'd like to minimize the overshoot.
Here are some design requirements:
- Power supplies +/-5Vdc
- Output level: 2Vpp
- Total gain of THS3217 is 10 (=2X5) or lower
- Output load 100 ohm
Their current setup is: Rf=140, Rg=34.8, the overshoot is ~15%
They can reduce the overshoot by increasing the gain, but the noise level has gone up.
What would you recommend a scheme that can reproduce a square wave without overshoot at maximum bandwidth possible?
Preference is a positive gain, but a negative gain is also okay.
