Ultra low noise preamplifier

The SL561 used in this circuit is a high-gain low-noise preamplifier designed for audio/video applications at frequencies up to 6 MHz. Figure 2-6B shows gain versus frequency for various values of C1, and Fig. 2-6C shows gain versus various values of RSET. Figure 2-6D shows the electrical characteristics. Figure 2-6E shows harmonic distortion.
