Nov 05, 2020. 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 …

Search carefully for devices with low noise for sensitive circuitry, and make sure they also have the bandwidth needed to achieve high gains. NE5532 (or LM833, although I usually do not recommend them) dual opamps are an excellent choice for low noise, but bear in mind that LM833 opamps in particular can be troublesome to keep stable.
Low-noise amplifier - Wikipedia
https://en.wikipedia.org/wiki/Low-noise_amplifier
A low-noise amplifier (LNA) is an electronic amplifier that amplifies a very low-power signal without significantly degrading its signal-to-noise ratio.An amplifier will increase the power of both the signal and the noise present at its input, but the amplifier will also introduce some additional noise. LNAs are designed to minimize that additional noise.
