Overview
The NE5532D8 is a dual high-performance, low-noise operational amplifier produced by Onsemi. It is internally compensated for unity gain and is known for its excellent noise performance, improved output drive capability, and higher small-signal and power bandwidths compared to standard operational amplifiers like the 1458. This makes it particularly suitable for high-quality and professional audio equipment, instrumentation and control circuits, and telephone channel amplifiers.
