Any opamp circuit that uses a plus and minus power supply can use a single positive supply if its (+) input is biased at half the supply voltage and input and output coupling capacitors are used. The circuit you posted uses very many extra parts so that its DC output averages 0VDC. When you use an output coupling capacitor then the output of it will have any DC blocked by the capacitor so the extra parts are not needed.
A 555 does not produce a sinewave output. Why didn't you make a sinewave oscillator instead?
Good point. Crossover distortion might be overcome in the circuit by class A bias, but the simulated slew rate is definitely beyond LM358 specifications (0.5 V/µs). Probably an incorrect OP model used.The LM358 produces crossover distortion and its poor slew rate does not allow high levels at 5kHz.
I am not sure exactly what you want to do. In another thread, you wanted a signal swing between zero and up. Here your simulation shows a bipolar output signal.
In any case, you can add a simple current booster to the op-amp signal as shown.
The distortion is about 1% THD. One of the factors causing this is that the 358 does not swing completely down to zero. It gets to about 50 -100 mV from zero. This can vary between different manufacturers.
It can also drive a 75 Ohm load with slightly more (1.3 % THD) distortion.
The LM358 produces crossover distortion and its poor slew rate does not allow high levels at 5kHz. The amplifier is missing negative feedback from its output.
Most good specimens of the LM358 from reputable manufacturers can still perform well at 5 kHz in this circuit.but the simulated slew rate is definitely beyond LM358 specifications (0.5 V/µs). Probably an incorrect OP model used.
You are right, 0.5V/µs refers to about 30 Vpp undistorted sine at 5 kHz.Most good specimens of the LM358 from reputable manufacturers can still perform well at 5 kHz in this circuit.
