The maximum power supply voltage for the LM358DRG3 is ±18V or 36V total supply voltage.
Yes, the LM358DRG3 is suitable for audio applications due to its high gain-bandwidth product and low noise characteristics.
Yes, the LM358DRG3 can be used as a comparator, but it's not the best choice due to its relatively slow response time and limited output current capability.
To protect the LM358DRG3 from overvoltage, use voltage clamping diodes or a voltage regulator to limit the input voltage to the recommended maximum rating.
The maximum output current of the LM358DRG3 is 20mA per channel.
