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.

Operating Ratings indicate conditions for which the device is func- tional, but do not guarantee specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which guar- antee 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 kΩ in series with 100 pF.

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 pre- vent excess power dissipation if the output is accidentally shorted.
