![]() ![]() This preamp amplifies that mV range signal to a somewhat high amplitude signal so when a power amplifier amplifies it the signal has less noise and distortions. Guitar pickups are electro magnetic devices that outputs a signal in mV range when the strings are moved. 2N5457 JFET transistor does the main task of amplifying the input signal from the guitar pickup. Such preamplifier circuit is given in below image.Īs you can see it only requires very small number of components. So let’s find out how to build a simple small guitar pre amplifier using 2N5457 JFET. Such as small amplifiers like guitar preamplifiers, podium microphone preamplifiers, condenser microphone preamplifiers etc. Low intermodular distortion and cross modulationĪs mentioned above 2N5457 is suitable and recommended for audio related switching applications.Low input capacitance and transfer capacitance.Drain and source pins are interchangeable.Let’s find out what are the key features of 2N5457 JFET transistor. You can see the physical appearance, pinout and the symbol of the 2N5457 JFET in below given image. ![]() It comes in a three pin TO-92 through hole package. It’s datasheet mentioned that it is most suitable for audio related switching applications. ![]() T12:41:29-05:00 T12:41:29-05:00 application/pdf amy 2N5457 Acrobat Distiller Command 3.01 for Solaris 2.2N5457 is a small JFET (Junction Field Effect Transistor) transistor.
