CHAPTER 4 Opamps and their properties
Introduction
Audio design has for many years relied on a very small number of opamp types; the TL072 and the 5532 dominated the audio small-signal scene for many years. The TL072, with its JFET inputs, was used wherever its negligible input bias currents and low cost were important. For a long time the 5534/5532 was much more expensive than the TL072, so the latter was used wherever feasible in an audio system, despite its inferior noise, distortion, and load-driving capabilities. The 5534/5532 was reserved for critical parts of the circuitry. Although it took many years, the price of the 5532 is now down to the point where you need a very good reason to choose any ...
