Leading edge charge injection for the ADG12xx products is shown in this slide. A design technique is implemented that uses an internal switch to absorb the injected charge and ensures minimal voltage glitch on the output. This plot shows how the charge injection on the ADG1208 compares to some industry standard parts. The datasheet normally shows the QINJ value when the input voltage is 0V. However, QINJ can be much higher at other input voltage levels so customers should be aware of the effect of charge injection over their complete signal range. The benefit of the ADG12xx family is that the QINJ is almost flat over the full signal range.
