Widely considered a "guru" of audio op-amp design, Jung has been a prolific, authoritative writer on analog design topics for nearly 35 years, specializing in op-amp and audio-related applications. His articles have appeared in numerous audio-oriented periodicals. His first article appeared in Electronic Design in 1968, and there have been many more since then. His analog-oriented column, "Walt's Tools and Tips," ran in Electronic Design from January 1997 through December 1998. Jung has also written several books, such as IC Op-Amp Cookbook and Audio IC Op-Amp Applications, both considered primary sources for a generation of professional audio engineers. In 1991, following a three-and-a-half-year tenure at Linear Technology Corp., Jung joined Analog Devices Inc., where he is a corporate staff applications engineer.
