Working Principles

The NJM5532DD is an operational amplifier that amplifies small input signals to a higher output level. It operates by using feedback to control the amplification process. The non-inverting input (IN+) and inverting input (IN-) receive the input signal, and the amplified output is obtained from the non-inverting output (OUT+). The operational amplifier requires a dual power supply (V+ and V-) to operate within the specified voltage range.
