Single-supply and rail-to-rail outputs are a great combination, but there are a few parameters that warrant a second look. Your question doesn’t specify whether …
The LM386 IC Low Power Audio Amplifier - DIYODE …

The LM386, and other single-rail amplifiers are designed so that the middle of the waveform sits at the half-way point between the positive supply rail, and ground. An AC signal can still be input, and will still have the relevant output.

B) It feeds the power rails directly into the op-amp inputs so there is no PSRR whatsoever. Using a virtual ground IC like the TLE2426 overcomes these issues but that adds cost and uses PCB space. So.. for anyone looking here in the future I've found 3 op-amps that look good for single-rail audio use. The AD824, the NJM2747 and the LMC6484
FAQ: Amplifiers What do rail-to-rail and single supply mean?

Figure 2 below shows a section of the Analog Devices datasheet for the ADA4622; a single-supply RRO op amp. The ADA4622 has a single supply voltage of 30 V (but the op amp splits that 30 V into two rails to swing between: +15 V and -15 V). Note that the typical V OH is very close to the rail at 14.97 V, but the worst you should experience is +14.95 on the upper rail. …

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:
