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.

Design Electrical Characteristics (Continued)
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which
guarantee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit
is given, however, the typical value is a good indication of device performance.
Note 2: All voltages are measured with respect to the ground pin, unless otherwise specified.
Note 3: If supply voltage is less than ±15V, it is equal to supply voltage.
Note 4: This is the permissible value at TA≤85˚C.
Note 5: Human body model, 1.5 kΩin series with 100 pF.

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. This resistor will also
prevent excess power dissipation if the output is accidentally
shorted.
Noise Measurement Circuit
00521827
Complete shielding is required to prevent induced pick up from external sources. Always check with oscilloscope for power line noise.
