Frequently Asked Questions
What is the intended primary application of the LM833 amplifier?
The LM833 is a dual operational amplifier particularly well-suited for audio systems, such as preamplification and filtering.
What are the main performance specifications (e.g., noise, distortion)?
It features low voltage noise (4.5 nV/√Hz), excellent phase/gain margins, and ultra-low distortion (0.002%).
Can I power the device using negative or positive supply rails?
Yes, it supports dual supplies of $\pm 18$ V to $\pm 36$ VCC for operation.
What is the recommended action if an input voltage is driven negative?
This condition is generally not destructive and normal output is restored when input voltages are above -0.3 V.
