The NE5534AD is a low-noise Operational Amplifier combines 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. This operational amplifier is 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 NE5534AD features input-protection diodes, out-put short-circuit protection and offset-voltage nulling capability with use of the BALANCE and COMP/BAL pins. In this amplifier a maximum limit is specified for the equivalent input noise voltage.
