hi
I have a problem of deciding the right IC and the circuit around it for one of my project. Its to do with deisgning and preamp for a dynamic microphone. with phantom power supply high pass filter and LED VU meter. thinking of using INA 103 or INA118 but there is NE5533 as well. got a circuitary from INA103 data sheet. plus which high pass filter I would need? (I think its 2nd order butterworth) should I stick with it as I have only two weeks to finish. any help will be appricaited.
