I have a doubt regarding OP-AMP circuitry.
1.when OPAMP is used as a buffer, it is always non-inverting configuration,why??
2. in buffer, inverting terminal is shorted with output terminal, in other words, feedback resistor is zero. And signal is given to the non-inverting terminal. But in some cases, though supply is given to the non-inverting terminal, still a feedbach resistor is connected, what is the advantages??please reply soon.
