Feature Description (continued)

8.2.5 Ultra-low Leakage Current

The TMUX1119 provides extremely low on-leakage and off-leakage currents. The TMUX1119 is capable of

switching signals from high source-impedance inputs into a high input-impedance op amp with minimal offset

error because of the ultra-low leakage currents. Figure 26 shows typical leakage currents of the TMUX1119

versus temperature.

8.2.6 Ultra-low Charge Injection

The TMUX1119 has a transmission gate topology, as shown in Figure 27. Any mismatch in the stray capacitance

associated with the NMOS and PMOS causes an output level change whenever the switch is opened or closed.
