Working Principles

The LM833P is a high-performance operational amplifier that amplifies the difference between its two input voltages. It utilizes a differential input stage followed by a gain stage and an output buffer. The differential input stage provides high open-loop gain, while the gain stage amplifies the signal further. The output buffer ensures that the amplified signal can drive low impedance loads without significant distortion.
