Hi there,
I've been looking all around the internet for an answer to this question but can't seem to find a clear one...
I'm trying to select op-amps for a project and one important spec if the gain bandwidth product (GBW). The normal calculation is pretty easy (using voltage-to-voltage gain), but how would I spec it for a transimpedance gain, since the gain is in dB-Ω.
For example an OPA656 has a GBW of 230MHz, what would that equate to in terms of a transimpedance GBW?
Thanks!
