NE5532AP Op. Amplifier
The NE5532AP is a dual high-performance low noise operational amplifier. By comparison with most of the standard operational amplifiers, such as the 1458, it displays better noise performance, improved output drive capability and markedly higher small-signal and power bandwidths.
This makes the NE5532AP especially suitable for application in high-fidelity and professional audio equipment, instrumentation and control circuits, and telephone channel amplifiers. The NE5532AP is internally compensated for gains equal to one. If very low noise is of prime importance, it is recommended because it has guaranteed noise voltage specifications.
