Turn-on time for the switch. This parameter is measured under the specified range of conditions and by the propagation
t
ON
delay between the digital control (IN) signal and analog output (D or S) signal when the switch is turning ON.
Turn-off time for the switch. This parameter is measured under the specified range of conditions and by the propagation
t
OFF
delay between the digital control (IN) signal and analog output (D or S) signal when the switch is turning OFF.
Charge injection is a measurement of unwanted signal coupling from the control (IN) input to the analog (S or D) output.
Q
C
This is measured in coulomb (C) and measured by the total charge induced due to switching of the control input. Charge

measured in a specific frequency and in dB.
BW Bandwidth of the switch. This is the frequency in which the gain of an ON channel is – 3 dB below the DC gain.
Total harmonic distortion describes the signal distortion caused by the analog switch. This is defined as the ratio of root
THD mean square (RMS) value of the second, third, and higher harmonic to the absolute magnitude of the fundamental
harmonic.
