Working Principles

The AD641AN is an operational amplifier that amplifies the difference between its two input voltages. It operates based on the principles of differential amplification and feedback control. The input signals are amplified by a high-gain internal amplifier, and the amplified output is fed back to the inverting input through a feedback network. This feedback mechanism allows the amplifier to maintain stability, accuracy, and desired characteristics.
