6.3.6 Ultra-Low Charge Injection

The TMUX1109 has a transmission gate topology, as shown in Figure 6-13. Any mismatch in the stray capacitance associated with the NMOS and PMOS causes an output level change whenever the switch is opened or closed.

The TMUX1109 has special charge-injection cancellation circuitry that reduces the source-to-drain charge injection to as low as 1pC at VS = 1V as shown in Figure 6-14.
