minimal voltage level for NJM4580 opamp

[vakulenko]

Hello, fiiends!
I need to power pre-amp based on NJM4580 chip. According to the datasheet, the chip is powered by a voltage of ±2 to ±18 volts. The input signal will be ±1V, the output no more than 3V. Most of the circuits I have seen use a voltage of ±12-15V. Will a supply voltage of ±6V be enough for me? Or will this negatively affect the quality of the output signal? I want to use the lowest possible voltage to reduce the size of the capacitors and transformer secondary winding.
Thanks for comments!

3v at the output + some voltage required by the transistors.
+- 6v would be enough .
If not you can use rail to rail op amps.
Why you need the output toas high as 3v ? .
Edit:
Check output voltage vs supply voltage.
Seems fine on +-5 , 6v .

Thanks a lot! This is exactly what I was looking for.

This is just with a small reserve. Short-term peak values. In reality it will of course be no more than 1,5-2V
