Working Principles

The MAX944ESD+TG52 is an operational amplifier that amplifies and filters input signals. It operates by taking the difference between the voltages at its inverting (IN-) and non-inverting (IN+) inputs, and amplifying this difference by a factor determined by its gain. The amplified signal is then available at the output pin (OUT). The op-amp requires a dual power supply, with positive voltage connected to V+ and negative voltage connected to V-. The ground reference is provided by the VEE pin.
