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.
Features:
D Wide Dynamic Range
D Low Input Noise Voltage
D High Slew Rate
D High Gain Bandwidth Product
D Wide Power Bandwidth
