NE5532DRG4 is an operational amplifier (OP AMP) in the category of instrumentation amplifiers, buffer amplifiers, and linear amplifiers. This low-distortion and high-sensitivity op amp is used in audio and instrumentation applications, such as power supplies and audio amplifiers. It consists of two internally-compensated and matched BTL amplifiers in various media. In addition to being an OP amp, the NE5532DRG4 is also a dual-channel device, allowing two separate circuits to independently and accurately process two signals.

The NE5532DRG4 operates on a wide supply range from ±4.75V to +32V for high power output and up to ±22V for optimum distortion and noise performance. The device also features protected outputs, which can safely deliver up to 27V and properly provide short-circuit protection while delivering a maximum of 400mA of current. Other features include a high input impedance of 50kohm, a low quiescent current of only 5mA, and a low output noise voltage compared to the NE5532DR, making it ideal for noise-sensitive applications.

The working principle of the NE5532DRG4 is based on the current-mode principle. Two current sources located in the differential amplifiers generate their output signals by sensing the current flow in the respective source and output transistors. This then implements a voltage controlled current source, allowing for a flat frequency response and fast settling time. This is, in general, precisely how the NE5532DRG4 OP amp works.

NE5532DRG4 can be used in multiple applications depending on the circuit design, which can range from high-performance applications such as preamplifiers and instrumentation amplifiers to consumer circuits such as prosound amplifiers. The device also functions well with low-level and medium-level signals, and its high gain accuracy is useful for both audio and industrial applications. Additionally, its low noise and high-resolution linearity are useful in rugged environments where accuracy and integrity are of utmost importance.

Overall, the NE5532DRG4 is a low-distortion and high-sensitivity OP amp which is used for numerous applications. It operates on a wide supply range from ±4.75V to +32V and features protected outputs, a high input impedance, low quiescent current, and low output noise voltage. Furthermore, the working principle of the NE5532DRG4 is based on the current-mode principle and is used in multiple applications ranging from preamplifiers to prosound amplifiers and industrial circuits.
