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 T
A
85C.
Note 5: Human body model, 1.5 k
in series with 100 pF.
