LM833 Dual Audio Operational Amplifier General Description Features 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 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. > 140dB j Wide dynamic range: j Low input noise 4.5nV/Hz voltage: j High slew rate: j High gain bandwidth: 7 V/s (typ); 5V/s (min) 15MHz (typ); 10MHz (min) j Wide power bandwidth: 120KHz j Low distortion: 0.002% j Low offset voltage: 0.3mV j Large phase margin: 60 j Available in 8 pin MSOP package Schematic Diagram (1/2 LM833) 00521801 (c) 2004 National Semiconductor Corporation DS005218 www.national.com LM833 Dual Audio Operational Amplifier January 2003 LM833 Connection Diagram 00521802 Order Number LM833M, LM833MX, LM833N, LM833MM or LM833MMX See NS Package Number M08A, N08E or MUA08A www.national.com 2 Storage Temperature Range TSTG If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications.

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

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