NE5532N

Dual, high-performance, low-noise operational amplifier (op-amp) widely regarded as the industry standard for professional-grade audio equipment due to its exceptional clarity and low distortion - Audio Performance: Features a typical input noise voltage of 5 nV/√Hz, making it ideal for high-fidelity audio preamplifiers.
Bandwidth & Speed: Offers a 10 MHz small-signal bandwidth and a slew rate of 9 V/µs.
Voltage Range: Operates on a wide supply voltage range from ±3V to ±20V (or up to 40V total span).
Output Drive: Capable of driving 600 Ω loads at 10V RMS with very low total harmonic distortion.
Internal Compensation: It is internally compensated for unity-gain stability, meaning it can be used in simple buffer circuits without oscillating.
