9.2 Typical Application

One useful application to take advantage of the TMUX405x features is multiplexing various signals into an ADC that is integrated into an MCU. Utilizing an integrated ADC in an MCU allows a system to minimize cost with a potential tradeoff of system performance when compared to an external ADC. The multiplexer allows for multiple inputs or sensors to be monitored with a single ADC pin of the device, which is critical in systems with limited I/O. The TMUX4052 is suitable for a similar design example using differential signals, or as two 4:1 multiplexers.
