Audio Designs With Opamps
https://sound-au.com/dwopa.htm
The operational amplifier was first used in the 1930's as the basis of analogue computers, and much development took place to design accurate gun aiming systems during the Second World War. Since integrated circuits were unknown at the time (this was before the invention of the transistor), the earliest versions were made using valves.

The Analog Audio Amplifier Front-end Reference Design demonstrates how to build an audio front end for the TPA32xx class-D amplifier. The AUDIO-OPA1632EVM is the board that was designed to test the results of this design. Design files for the board are available in the reference design product (...) View design.

By Douglas Self 05.25.2011 0. Audio design has for many years relied on a very small number of op-amp 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 …

The OP275 Op-Amp The Analog Devices OP275 is one of the few op-amps specifically marketed as an audio device. Its most interesting characteristic is the Butler input stage, which combines bipolar and JFET devices. The idea is that the bipolars give accuracy and low noise, while the JFETs give speed and 'the sound quality of JFETs'.

Below is the symbol used to represent an operational amplifier. The two inputs are the inverting (V-) and non-inverting (V+) terminals, and the output is Vout. The supplies are discussed further in the pages ahead. Figure 1. Op-amp Symbol The op-amp can be thought of as a “black box” having two inputs and one output as seen in Figure 2 below:

OpAmp design. It can provide high gain and high output swing. It is an excellent example to illustrate many important design concepts that area also directly applicable to other designs. The two-stage refers to the number of gain stages in the OpAmp. The output buffer is normally present only when resistive loads needs to be driver.

The amp in figure 9b (by PRR) adds an opamp gain stage. The design exploits the ability of an opamp to serve as a voltage source. Once Id is set via Rs, the MOSFET gate draws the bias voltage it needs directly from the opamp’s output without a biasing network. (The MOSFET’s device specs will have a graph of gate voltage V G vs. idling current I D.) The feedback network …
