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 tech-
niques to deliver low noise, high speed and wide bandwidth
without increasing external components or decreasing stabil-
ity. 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.

  • Page 9: Application Hints

    521826 Application Hints The LM833 is a high speed op amp with excellent phase margin and stability. Capacitive loads up to 50 pF will cause little change in the phase characteristics of the amplifiers and are therefore allowable. Capacitive loads greater than 50 pF must be isolated from the output. The most straightforward way to do this is to put a resistor in series with the output.
