Working Principles

The LP358DR is based on the operational amplifier (op-amp) circuit configuration. It utilizes differential inputs to amplify the voltage difference between its inputs. The amplified output is then fed back to the inverting or non-inverting input, depending on the desired configuration. This feedback mechanism allows the op-amp to perform various functions such as amplification, filtering, and signal conditioning.
