17.3.4 Flat On-Resistance

The TMUX6612-Q1 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 precision 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 TMUX6612-Q1 exhibits an extremely linear response.
