Hi, I have been looking for a schematic for a transimpedance amp for the national or BB chips. I have the OPA549 and I was wondering if the high current output could make them more appropriate for a current drive amp.
The few schematics that I found were incomplete. Can someone show me a proper schematic and hint me how to calculate the gain.
What should the input impedance (from pre) for the transimpedace be (to be good)?
