NTE891M & NTE891SM

Integrated Circuit

Dual Audio Operational Amplifier

Description:

The NTE891M and NTE891SM are dual general purpose operational amplifiers designed with partic-

ular emphasis on performance in audio systems. Thiese devices deliver low noise, high speed and

wide bandwidth without increasing external components for all closed loop gains and is therefore opti-

mized for all preamp and high level stages in PCM and HiFi systems.
