Hi, i'm trying to make a buffer amplifier using ic LM741. I want to input a 1Mhz 10Vpp sine wave. I would like to know, is it the output buffer voltage will remain same 10Vpp at 1Mhz frequency?

No, LM741 is an Op Amp designed to work with signals with frequencies in the audible range.I would like to know, is it the output buffer voltage will remain same 10Vpp at 1Mhz frequency?
I don't think so. The audible range goes to 20kHz. The slew rate graph of the 741 opamp that was released 47 years ago shows that it has trouble with high level signals above only 9kHz.No, LM741 is an Op Amp designed to work with signals with frequencies in the audible range.
In the 741 ages, no designer had seriously considered to drive 1 MHz 10Vpp with an OP.This was the most powerful and versatile opamp of yesteryears. Sorry, it cannot handle 1MHz.
