Dual Audio Operational Amplifier
LM833 Dual Audio Operational Amplifier
August 1997
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 bandwidth without increasing external components or decreasing
stability. The LM833 is internally compensated for all closed
loop gains and is thereforeoptimizedforallpreampand high
level stages in PCM and HiFi systems.
The LM833 is pin-for-pin compatible with industry standard
dual operational amplifiers.

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.
DS005218-26
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. This resistor will also prevent excess power dissipation if the output is accidentally
shorted.

Noise Measurement Circuit
Complete shielding is required to prevent induced pick up from external sources. Always check with oscilloscope for power line noise.
