National Semiconductor's LM4562 dual 34V high-fidelity audio operational amplifier is said to practically eliminate distortion, with total harmonic distortion plus noise of 0.00003 percent. That performance reportedly exceeds the performance of hand-built audiophile discrete methodologies, thus setting a new standard for sound quality in high-end professional and high-quality consumer audio markets. It has wide 55-MHz gain bandwidth, 10-MHz power bandwidth.
What should be the perception of a product’s real-world performance with regard to the published spec sheet? While it is easy to assume that the product will operate according to spec, what variables should be considered, and is that a designer obligation or a customer responsibility? Or both?
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
