Working Principles

The MAX44211ETP+T is an operational amplifier that amplifies small input signals to a higher level. It operates by using a differential input stage, which amplifies the voltage difference between the IN+ and IN- pins. The amplified signal is then passed through additional stages to provide the desired gain and output characteristics. The rail-to-rail output allows the amplified signal to swing close to the supply voltages, maximizing the dynamic range.
