The cool thing about them is the odds are good you’ve used one, even if you weren’t fully aware of it. Chances are you own an audio interface and microphone, and you’ve plugged that mic into the interface to record. That’s the single most important use of a preamplifier right t...
An interesting fact is that all the top-level preamps come with phantom power capabilities. And nowadays almost each high-quality recording software has a built-in preamp to make the process better. In any device that has a microphone input, there is a mic preamplifier. You may also like:...
Low noise amplifier, amplifier with low noise figure. It is generally used as high-frequency or intermediate frequency preamplifier of various radio receivers and amplification circuit of high-sensitivity electronic detection equipment. When amplifying a weak signal, the noise of the amplifier itself ma...
The input impedance of theoperational amplifieris extremely high, and there is basically no current in the inverting input terminal (-). Therefore, when flows to R2 via point A, the currents of I1 and I2 are basically equal. Based on the above conditions, using Ohm's law for R2, we ...
