Working Principles

The MAX4643ETA+ operates by utilizing MOSFET technology to control the flow of analog signals. When an enable (EN) pin is activated, the corresponding switch connects the input (IN) pin to the output (OUT) pin, allowing the signal to pass through. Conversely, when the enable pin is deactivated, the switch disconnects the input and output pins, isolating the signal.
