Working Principles

The SA5534D is an audio operational amplifier designed to amplify and condition audio signals. It operates by taking the difference between the voltages at its inverting and non-inverting inputs and amplifying this difference by a fixed gain. The amplified output signal is then fed to external circuitry for further processing or driving a load.
