NTE997 Integrated Circuit Quad Operational Amplifier
Description: The NTE997 is a monolithic quad operational amplifier in a 14-Lead DIP type package consisting of four independent high gain, internally compensated operational amplifiers. The specifically designed low noise input transistors allow the NTE997 to be used in low noise signal processing applications such as audio preamplifiers and signal conditioners. The simplified output stage completely eliminates crossover distortion under any load conditions, has large source and sink capacity, and is short- circuit protected. A novel current source stabilizes output parameters over a wide power supply voltage range.
