Hello, Anthony here again, I was just wondering if anyone out there knows about the most current op-amps. I look in the catalogs and see op-amps that claim to have "Megahertz of BW". I am almost positive that this DOES NOT mean that it can even buffer, say a 10.7MHz signal, much less amplify or filter one. Are there any that are capable of operating at 455kHz yet? How well? Where can I find info about how to interpret such specifications, (especially on the net). Should I find any I will gladly post an article about it on my website. I know this is a little OT, but I feel that Op-Amps play a very important role when it comes to embedded processors such as the PIC, almost as important as the 78L05 regulator and the 2K pull-up!
