Low Total Harmonic Distortion: 0.003% TypicalĦ. Wide Common-Mode and Differential Voltage Rangesĥ. Offset adjustment and external compensation options are available within the TL07x family.Ģ. The low harmonic distortion and low noise make the TL072 series ideally suited for high-fidelity and audio pre-amplifier applications. The devices feature high slew rates, low-input bias and offset currents, and low offset-voltage temperature coefficient. Each of these JFET-input operational amplifiers incorporates well-matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit.
Of course, the contribution of the surrounding circuitry still needs to be considered.The TL072 JFET-input operational amplifier family is designed to offer a wider selection than any previously developed operational amplifier family. Will post again if I remember where they were.įor noise-sensitive synth applications at higher impedances, the LME49720 low voltage noise of 2.7nV/√Hz is much better than TL072 because 18nV/√Hz may have been low noise 30 years ago but isn't really now. frequency graphs for TL072, NE5532 and LM4562 but can't place where I saw them. It also has single and quad subtypes that has one and four operational amplifiers are TL071 and TL074. The inner circuit of this component has 2 operational amplifiers that can be worked through use of one or two power supplies. The fact that 5532 is only stabilised for a closed loop gain of 3x, and has much lower input impedance than JFET designs, is not a concern in that application. The TL072 is a very commonly used operational amplifier that comes in dual in-line packaging also has eight pinouts. Which is why commercial pro audio is full of low cost NE5532 opamps and not TL072. So devices with low voltage noise, higher current noise, and much lower resistor values than are typical in modular synths (for low Johnson noise) can give significantly better results. An audio preamp typically needs low noise and high gain, and typically doesn't care about current draw. Note that my original statement was not "I prefer NE5532 over TL072 for everything" but instead "If you are using it in an audio preamp, wouldn't an NE5532, or LM4562, or LME49720 be a better choice?". Plop, I guess marketing slogans have greater longevity than technical specifications do. Now both are specced at the latter value. As you say, when introduced they had somewhat different noise specs of 25nv/√Hz vs. Environmental Documents Environmental Documents.
