Low Noise Audio Preamplifier Circuit. A preamplifier circuit with a very low noise characteristic can be built by simply combining a FET transistor with a bipolar one. The input impedance of the preamp circuit is almost the same as the gate impedance of the FET transistor (around 1MΩ) The output impedance at the other end is about 1KΩ.

The circuit below is a low noise low distortion 60 dB (Av=1000) gain block that can be used as an audio preamplifier for very low signal or noise measurements. A high performance LM4562NA dual op-amp is used. Each half of the op-amp uses a different circuit to demonstrate different usage. (The circuit could be easily duplicated in each half of the dual circuit for stereo …
