9.3.2 Flat On-Resistance

The TMUX821x devices are 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 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.

The flattest On-Resistance region extends from VSS to roughly 5 V below VDD. Once the signal is within 5 V of VDD the On-Resistance will exponentially increase and may impact desired signal transmission.
