NE5532DR2G is a monolithic linear integrated circuit used to provide precision performance in audio systems which include preamplifiers and power amplifiers, tone and volume control, sound mixer and tone generators. This IC is capable of handling diverse audio functions like clipping, filtering, and level shifting.

The device includes two low noise, voltage feedback operational amplifiers, plus additional features such as input offset compensation, common mode feedback and temperature tracking. In addition, it has an integrated voltage regulator and enable/disable logic within the package.

The NE5532DR2G provides excellent performance both in small AC and DC signals. This performance comes from its features like large bandwidth, low noise and distortion, and low power consumption. It also has good input protection and isolation between the 2 amplifiers.

The NE5532DR2G is designed for applications in consumer and professional audio systems. It is also ideal for other applications such as filters, signal conditioning and video systems. Furthermore, it can be used for optical signal conditioning and for audio instrumentation.

Application Fields of NE5532DR2G

NE5532DR2G is an ideal IC for audio applications such as audio amps, preamplifiers, surround sound systems, active crossover networks, tone control, and level control. It also finds wide usage in professional studio equipment such as PA amplifiers, studio mixers, and powered speaker systems.

The NE5532DR2G is also suitable for audio-video applications such as video equalizers, video conditioners, switchers, and monitors. Further, it can also be used in level translating and buffer applications, control systems, and industrial machinery.

Working Principle

NE5532DR2G contains two low noise and high performance voltage feedback amplifiers. The gain of each of these op-amps is determined by the feedback network connected to the amplifier\'s output. This feedback network is adjustable in order to set the desired gain. The maximum gain of the devices is 120dB.

The NE5532DR2G has a wide common mode rejection ratio (CMRR) making it suitable for applications such as line level, microphone level and speaker level signals. It also has a very low noise figure and a low distortion which make it ideal for audio applications.

The IC has two enable/disable (E/D) pins which allow the device to be operated in two different modes. In one mode, both amplifiers are disabled and the state of the output is left undetermined. In the other mode, one amplifier is enabled and the other can be disabled.

The device is powered from a single voltage source and its operation is unaffected by its thermal environment. The NE5532DR2G is also very stable, has a good heat dissipation, and high reliability making it suitable for long term continuous operation.

Conclusion

The NE5532DR2G is a sophisticated linear integrated circuit designed to provide excellent performance both in small AC and DC signals. It finds wide application in audio-video system, audio amplifiers, preamplifiers, surround sound systems, active crossover networks, tone control, and level control. The device has two low noise and high performance voltage feedback amplifiers and can be operated in two different modes with two enable/disable pins. The NE5532DR2G offers excellent thermal stability and reliability, low power consumption, low noise figure and distortion, and wide common mode rejection ratio. All these features make it an ideal IC for a wide variety of applications.
