INTEGRATED CIRCUITS NE/SA/SE5532/5532A Internally-compensated dual low noise operational amplifier Product specification IC11 Data Handbook 1997 Sept 29 Philips Semiconductors Philips Semiconductors Product specification Internally-compensated dual low noise operational amplifier NE/SA/SE5532/5532A DESCRIPTION The 5532 is a dual high-performance low noise operational amplifier. Compared to most of the standard operational amplifiers, such as the 1458, it shows better noise performance, improved output drive capability and considerably higher small-signal and power bandwidths. This makes the device especially suitable for application in high-quality and professional audio equipment, instrumentation and control circuits, and telephone channel amplifiers. The op amp is internally compe [ ... ]
