Ray Stata Op Amp Articles, 1960s

These are a collection of technical articles written by Ray Stata shortly after the founding of ADI in 1965. The initial products from ADI were modular operational amplifiers, and the material is timeless, although some of the terminology has been changed. Of particular interest is the "Speaks Out" article. This was a popular series in EEE magazine where various "experts" spoke out on topics of interest at the time. Ray discusses a number of pitfalls in applying op amps that are still troublesome to engineers today.
