OPA549/541 at unity gain - schematic needed.

[nina]

Hi,

Could any one show me the schematic of OPA549 at unity gain esp. on the value R feedback? Also, any special concerns in running this consition?

Thanks in advance!

Calculateing gain for the OPA549 is the same as for any opamp, but make sure that the OPA549 is unity gain stable as many power amp IC"s are not unity gain stable, check the datasheet....

Here is a calculator for calculateing gain:

Make sure that you select the correct setting for inverting or noninverting configs....


Cheers

The OPAs are unity gain stable, and all the info you need is in the datasheet.
