You can add external multiplexers, but se normally require additional control lines from  CPU. Also,  time required for switching channels may limit  system's throughput rate. The circuit in Figure 1 allows you to increase  effective size of an ADC's multiplexer without requiring any additional time or control lines from  CPU.

 ADC Shuts Down Analog Circuitry:  03/03/94 EDN-Design Ideas / (added 4/02) Shutting down circuitry not in use is a common method of saving power in portable and battery-powered equipment. Although many ADCs have  ability to power down, most or analog components, such as op amps and sensors, do not. The conventional approach to shutting down analog signal-conditioning circuits is to power m using a voltage regulator that has shutdown capability, and to control this regulator using a dedicated signal line from  microcontroller. Often, how ever, this additional I/O line isn't available....
