The NE5532 device is high-performance operational amplifier combining excellent DC and AC characteristics. The NE5532 has back-to-back protection diodes on its inputs that cause many circuits to fail, and it consumes significantly more supply current than a TL072. The NE5532, which has bipolar transistors on its input, has 'popcorn' noise below 30Hz, whereas the TL072 has much less. The large input cap's low impedance keeps the input current noise to a minimum. A NE5532 is frequently seen as a phonograph cartridge, tape head, or microphone preamp with a massive input coupling capacitor that takes nearly forever to charge. The TL072 is quieter when the source impedance is greater than about 18.5k. However, when the source impedance is around 18.5k ohms, they have equal noise levels because the input current noise adds to the NE5532's input voltage noise. As a result, if the source impedance is extremely low (specified at 20 ohms), the NE5532 is three times quieter. Well, the NE5532's bipolar transistor inputs draw input current and are not the same as the TL072's JFET inputs, which have no input current. TL072 is also a very popular op amp, which often used to compare with NE5532, trying to know which one of them is quieter.

In addition, NE5532 has a warm tone and high fidelity when used for audio amplification. Therefore, NE5532 is very suitable for high-quality and professional audio equipment, instruments, control circuits and telephone channel amplifiers. Similar to many standard op amps, but NE5532 has the following unique features: better noise performance, excellent output drive capability, relatively high small signal bandwidth, large power supply voltage range, and so on. NE5532 is a high-performance low-noise dual operational amplifier (dual operational amplifier) integrated circuit. Today, we will walk you into the introduction of the popular dual op amp NE5532, you will learn its pinout, features, application, circuit diagram and its differences with TL072 and more.
