The NE5534, NE5534A, SA5534, and SA5534A are high-performance operational amplifiers combining
excellent dc and ac characteristics. Some of the features include 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).
For the NE5534A and SA5534A, a maximum limit is specified for the equivalent input noise voltage.
