Please help (voltage amplification)

[m_sh84]

Hello everyone

Can you please tell me how can i connect a (Coil Microphone) to OP-AMP 741 , in order to amplify the electrical voltage output of the microphone . I don't want the output as voice signal, I just want the signal as voltage how shall I make the connection? And what is the maximum gain I can get from LM741? Will it work if I use 1k ohm input and 470 K ohm output?


Thanks in advance

Bye-bye

First thing, DON'T use a 741, it's an incredibly old, low spec opamp, use a far better more modern device - something like a TL071?.

Second thing, what are you trying to do, your requirements are rather confusing?.
