The NTE891M and NTE891SM are single, highperformance, low noise operational amplifiers. Compared to other operational amplifier, these devices show better noise performance, improved output drive capability and considerably higher smallsignal and power bandwidths. This makes the devices especially suitable for applications in high quality and professional audio equipment, in instrumentation and control circuits and telephone channel amplifiers. The OP amps are internally compensated for gain equal to, or higher than, three. Features:
