This parameter is measured under the specified range of conditions and by the propagation delay between the digital control (IN) signal and analog output (COM or NC) signal when the switch is turning OFF. QC Charge injection is a measurement of unwanted signal coupling from the control (IN) input to the analog (NC or COM) output. This is measured in coulomb (C) and measured by the total charge induced due to switching of the control input. Charge injection, QC = CL × ∆VCOM, CL is the load capacitance, and ∆VCOM is the change in analog output voltage.

This is measured in dB in a specific frequency, with the corresponding channel (NC to COM) in the OFF state. BW Bandwidth of the switch. This is the frequency in which the gain of an ON channel is −3 dB below the DC gain. THD Total harmonic distortion describes the signal distortion caused by the analog switch.
