The NE5534P is a high-performance operational amplifier from Texas Instruments. Some of the features include excellent DC and AC characteristics, very low noise, high output-drive capability, high unity-gain and maximum-output-swing bandwidths, low distortion, and high slew rate. These operational amplifiers are compensated internally for a gain equal to or greater than three. Optimization of the frequency response for various applications can be obtained by use of an external compensation capacitor between COMP and COMP/BAL. The devices feature input-protection diodes, output short-circuit protection, and offset-voltage nulling capability with use of the BALANCE and COMP/BAL pins (see the application circuit diagram in the below pdf). The NE5534 line of opamps has become a staple used throughout the professional audio world since it's inception.
