Working Principles

The MAX349CPN is an analog multiplexer/demultiplexer IC that routes one of four input signals to a single output. It operates by selectively connecting the desired input channel to the output based on the control signal provided to the Enable pin. The rail-to-rail input/output capability ensures that the full range of input voltages can be accurately processed and transmitted. The low-power consumption makes it suitable for battery-powered devices, while the precision signal conditioning guarantees accurate data acquisition.
