hi,
I want to find operational amplifier that can amplifying 100kHz sinewave. What criteria that should I look? Thanks. I hope you all can help me.
 

Gain bandwith product should be considerably higher than intended gain multiplied with 100 kHz. Most OP will do except for slow ones. E. g. a "slow" 741 with 1 MHz GBW would be absolutely limited to a gain below 10 and should be used for a gain not higher than 2 up to 5.
 

Thanks FvM...
I already calculate using formula before. I'm also trying voltage follower circuit but i will become attenuation when above the audio signal...this I used normal 741..
