Working Principles

The MAX4521ESE+T is a precision analog switch that allows the user to route signals between different paths. It consists of two independent SPST switches controlled by input signals (IN1 and IN2). When the control input is high, the corresponding switch is closed, connecting the common terminal (COM1 or COM2) to the normally open terminal (NO1 or NO2). Conversely, when the control input is low, the switch is open, isolating the common terminal from the normally open terminal.

The low on-resistance of the MAX4521ESE+T ensures minimal signal distortion during switching, while its high bandwidth enables accurate transmission of high-frequency signals. The break-before-make switching action prevents shorting of signals during transition, ensuring reliable operation.
