Ultra low noise wideband preamplifier


Posted on Feb 7, 2014

The ZN459/CP used in this circuit is a high-gain low-noise preamplifier designed for audio/video applications at frequencies up to 15MHz. Figures 2-7B and 2-7C show typical PC board layouts for the ZN459 and ZN459CP (DIP), respectively. Figure 2-7D shows gain versus frequcncy.
