I am currently designing an audio amplifier using the LM324. I am operating from a single supply of 9 V. Here is the schematic: Here are the design steps I took: I …
Single-Supply Operation of Operational Amplifiers
https://www.ti.com/lit/an/sboa059/sboa059.pdf
tional amplifiers concerns operation from a single supply voltage. “Can the model OPAxyz be operated from a single supply?” The answer is almost always yes. Operation of op amps from single supply voltages is useful when negative supply voltages are not available. Furthermore, certain ap-plications using high voltage and high current op amps can

https://electronics.stackexchange.com/questions/153911/single-supply-op-amp-audio-amplifier
I am trying to create an op-amp amplifier that would work from single 5V supply, and would be able to amplify -100mV to +100mV audio signal to around a 1V peak-peak or so. I've came across this circuit from this article, that could seem to work, but am having trouble calculating the actual values:

An amplifier running from a single-ended supply must use an output coupling capacitor because the output must be at 1/2 Vcc for the amp to operate in a linear fashion. Dual amps get to run the output at 0 V and, naturally, have no need for an output coupling capacitor. Capacitors can limit low frequency response and electrolytic capacitors can cause distortion …

This is an old chip that has been a popular choice for low-power audio applications for many years. There are many other audio amp ICs on the market (LM380 and LM383 are similar but higher-power amps from National), but the LM386 is sufficient for our purposes. It comes in three-flavors, the LM386-1, LM386-2, and LM386-3, which can provide 0.3W,

A single-supply circuit (right side of Figure 1) connects the op-amp power pins to a positive voltage and ground. The positive voltage is connected to V CC+, and ground is connected to V CC-or GND. A virtual ground, halfway between the positive supply voltage and ground, is the reference for the input and output voltages.

Power Supply . The power supply used for this single MOSFET class A power amplifier circuit is 18VAC and 160VA EI transformer attached to a bridge rectifier of 25 amp to generate DC power of 24 Volts. To filter and smooth the power we used 10000µF capacitors and Hammond make 10mH choke of 5 amp over pi filter setting [Cap - Choke - Cap]. The bias was …
