The TL071 is not very modern, but it is good for audio (and general purpose), is cheap, and is easily available (even in through-hole packaging).what modern single op-amp should i replace with this one? :-D
the signal comes for a Signal Generator or test with mp3 player.
This op-amp is connected to a push-pull amp, with 6.125 watts output and input of 7volts peak-coming from op amp.
Parts is not so limited, we order it in Manila or buy it online, i choose LM324 because its easy to solve and this op-amp uses only 2 resistors
what modern single op-amp should i replace with this one? :-D can u suggest some?
During my entire career designing and building audio circuits, I used thousands of TL071, TL072 and TL074 from American manufacturers. They all worked perfectly and none failed.JFET op-amps [like the TL071/2/4] have a very high Zin, but you don't need that. I have heard reports they can be unstable.
As FvM mentioned, it's a really good idea to split the gain into two stages e.g. one opamp with a gain of 20 followed by another with a gain of 10. That not only improves the bandwidth, but it also reduces distortion a lot. It doesn't cost much extra since the single, dual and quad opamps are all about the same price, so you just need two extra resistors.
