9.3.1 Flat ON- Resistance

The TMUX7348F and TMUX7349F are designed with a special switch architecture to produce ultra-flat on-resistance (RON) across most of the switch input operation region. The flat RON response allows the device to be used in precision sensor applications since the RON is controlled regardless of the signals sampled. The architecture is implemented without a charge pump so no unwanted noise is produced from the device to affect sampling accuracy.
