Working Principles

The HA1-4905-5 is an operational amplifier (op-amp) that amplifies the difference between its two input terminals. It operates based on the principles of differential amplification and feedback control. The non-inverting input receives the signal to be amplified, while the inverting input provides a reference voltage. The op-amp amplifies the voltage difference between these inputs and produces an output signal proportional to this difference.
