9.3 Feature Description

9.3.1 Ultralow Leakage Current

The MUX50x provide extremely low on- and off-leakage currents. The MUX50x are capable of switching signals

from high source-impedance inputs into a high input-impedance op amp with minimal offset error because of

these ultralow leakage currents. Figure 37 shows typical leakage currents of the MUX50x versus temperature.

Figure 37. Leakage Current vs Temperature

9.3.2 Ultralow Charge Injection

The MUX50x have a simple transmission gate topology, as shown in Figure 38. Any mismatch in the stray

capacitance associated with the NMOS and PMOS transistors creates an output level change whenever the

switch is opened or closed.
