THS3001 Virtual Ground

Other Parts Discussed in Thread: THS3001

Can I use a virtual ground to use the THS3001 with a 12 volt single supply?

I don't know if Current Feedback Amplifiers work well with virtual ground due to virtual ground requires capacitors between real gound and the Feeback capacitors. I don't want oscillation for the capacitors.

Regards.

Hello Alfredo,
I am not quite sure what you mean. Can you please draw out a circuit for clearer understanding.

I'm attaching the document, I mean single supply operation.

Alfredo,
Looks good to me. You are using the resistive divider on the non-inverting input to set the bias point. Why are you using the R7 and C4 components in the circuit?

R7 is the LT1253 suggested 100 ohm load.
