DUAL LOW-NOISE OPERATIONAL AMPLIFIERS

General Description: The NE5532, NE5532A, SA5532, and SA5532A are high-performance operational amplifiers combining excellent  dc and ac characteristics. They feature very low noise, high output-drive capability, high unity-gain and  maximum-output-swing bandwidths, low distortion, high slew rate, input-protection diodes, and output  short-circuit protection. These operational amplifiers are compensated internally for unity-gain operation. These  devices have specified maximum limits for equivalent input noise voltage.
