Single Low Noise
Operational Amplifier
The NE/SA/SE5534/5534A are single high-performance low noise
operational amplifiers. Compared to other operational amplifiers,
such as TL083, they show better noise performance, improved output
drive capability, and considerably higher small-signal and power
bandwidths.
This makes the devices 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 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.).
