Working Principles

The LF25ABDT is an operational amplifier that amplifies and conditions electrical signals. It operates based on the principles of differential amplification and feedback. The input signals are applied to the inverting and non-inverting inputs, and the amplifier amplifies the voltage difference between these inputs. The amplified output signal is then fed back to the input through a feedback network, which helps control the gain and stability of the amplifier.
