I have had an error and the operational one is not the opa4277, it is the opa4227. The opa4227 has a Quiescent Current very high, but even so it is normal to reach high temperatures? or is a heatsink necessary?

Unfortunately the only document available for this device is the data sheet.
In addition this device is no longer in active state. So if you're looking for a replacement you can take a look at OPA1604 for a SOIC replacement and OPA4227 for…
OPA1604 is the specified replacement for LME49740 in SOIC package. If you're looking for a PDIP replacement then you can take a look at OPA4227.
Regarding the minimum GBW of the 4th stage:
The minimum GBW calculation used by FilterPro is the same for the Sallen-Key and MFB typologies. The GBW is calculated from: GBW = Ao x Q x fn x 100, where Ao is the gain of the stage (V/V), Q is…

I have a phase circuit that I have designed that uses four Op Amps to take an AC Input in the range of 50-60hz and then produce copies of that signal in but each phase shifted by 120 degrees…
