OPA1632 for balanced RIAA preamp.?
 
Hi all,

How would an OPA1632 (as Per-Anders brought up in the SS forum) work in a RIAA preamp.?

It's balanced and is only 1.3nV/Hz with great performance.

I think it must be great for a phono preamp using balanced...!

/Michael

PS: where do I find matemathical symbols etc. like square root??

This circuit looks like it only works in the inverting configuration so it would be difficult to apply it to many topologies.
