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 ...

THE DESIGN OF LOW-NOISE AUDIO-FREQUENCY AMPLIFIERS considering current ratios, without explicitly referring to the magnitudes of the voltages appearing at the amplifier input terminals. A great deal of confusion has arisen over the rela tion between noise figure and input resistance. It should be clear from Fig. 3 that if an amplifier has a
