[SOLVED] OP Amp biasing question

[FvM]

Will a circuit like this work?

Basically yes. Bypass capacitors for power supply and possibly for the voltage divider should add.

With a high speed OP (e.g. LM7171), feedback resistors above 1-2 k will cause loop instability due to the feedback pole. If you intend a high amplifier input impedance, you better go for a non-inverting configuration with these. High speed OP are also rather succeptible to capacitive loads.

The unity gain stable LM6171 may be a somewhat more convenient alternative.

Yes, that should work.
