7.3.4 Flat On-Resistance

The TMUXS7614D 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 no unwanted noise is produced from the device to affect sampling accuracy.

This architecture also ensures that RON stays the same regardless of the supply voltage. The flattest on-resistance region extends from VSS to roughly 5V below VDD. The on-resistance will exponentially increase when the signal is within 5V of VDD, which may impact the desired signal transmission.
