NE5532 Vs. TL072: What Is The Difference?

The NE5532 is a high-performance, low-noise operational amplifier with twin channels. It outperforms most typical operational amplifiers, including 1458, in terms of noise performance, output drive capability, and small-signal and power bandwidths.

As a result, the device is particularly well-suited for use in high-quality and professional audio equipment, instrumentation and control circuits, and telephone channel amplifiers. For gains of one, the op amp is internally adjusted. If very low noise is critical, the 5532A variant is recommended because it has guaranteed noise voltage standards.

The TL072 is a high-speed J–FET input dual operational amplifier with well-matched high voltage J–FET and bipolar transistors in a monolithic integrated circuit. High slew rates, low input bias and offset currents, and a low offset voltage temperature coefficient characterize the devices.

The NE5532 outperforms the TLO72 in almost every aspect of audio application, with the only significant exception being the 5532s' unusually large input current requirement. The TLO72 has extremely little load driving capability, is prone to latching up if the inputs are overloaded, and has a slew of other "features" that make it unsuitable for audio.

TL072 is another well-known operational amplifier that is frequently compared to the NE5532 in order to determine which is quieter. The bipolar transistor inputs of the NE5532, on the other hand, draw input current and are not the same as the JFET inputs of the TL072, which have no input current. As a result, the NE5532 is three times quieter when the source impedance is exceptionally low (defined at 20 ohms). They have equal noise levels when the source impedance is roughly 18.5k ohms, because the input current noise adds to the NE5532's input voltage noise. When the source impedance is greater than roughly 18.5k, the TL072 is quieter. A NE5532 is commonly seen as a phonograph cartridge, tape head, or microphone preamp with a huge input coupling capacitor that takes an eternity to charge. The low impedance of the large input cap reduces input current noise.
