LM833
Dual Audio Operational Amplifier
General Description
The LM833 is a dual general purpose operational amplifier
designed with particular emphasis on performance in audio
systems.
This dual amplifier IC utilizes new circuit and processing
techniques to deliver low noise, high speed and wide band-
width without increasing external components or decreasing
stability. The LM833 is internally compensated for all closed
loop gains and is therefore optimized for all preamp and high
level stages in PCM and HiFi systems.
The LM833 is pin-for-pin compatible with industry standard
dual operational amplifiers.
