7.3.4 Flat On-Resistance

The TMUX550x is designed with a special switch architecture to produce ultra-flat on-resistance (RON) across most of the switch input operating region. The flat RON response allows the device to be used in a wide variety of applications since the RON is controlled regardless of the signals sampled. The architecture is implemented without a charge pump so unwanted noise is not produced from the device to affect sampling accuracy.

This architecture also keeps RON the same regardless of the supply voltage. The flattest on-resistance region extends roughly from 5V above VSS to 5V below VDD. As long as this headroom is maintained, the TMUX550x exhibits an extremely linear response.
