The maximum power supply voltage for the TL064MJB is ±18V, or 36V total.
Yes, the TL064MJB is suitable for audio applications due to its low noise and distortion characteristics.
While the TL064MJB can be used as a comparator, it's not the best choice due to its relatively slow slew rate and limited bandwidth. A dedicated comparator like the LM339 would be a better choice.
To ensure stability, make sure to follow proper compensation techniques, such as adding a capacitor in the feedback loop, and ensure that the gain and phase margins are sufficient.
The TL064MJB is rated for operation up to 125°C, but its performance may degrade at high temperatures. Be sure to check the datasheet for temperature-related specifications and consider using a more temperature-stable op-amp if necessary.
