The NE5534 are single high-performance low noise operational amplifiers. it shows better noise performance, improved output drive capability, and considerably higher small-signal and power bandwidths.
This makes NE5534 especially suitable for application in high quality and professional audio equipment, in instrumentation and control circuits, and telephone channel amplifiers.
The op-amps are internally compensated for a gain equal to, or higher than, three. The frequency response can be optimized with an external compensation capacitor for various applications (unity gain amplifier, capacitive load, slew rate, low overshoot, etc.).
