Flatness is defined as the difference between the maximum and minimum value of on resistance as
measured over the specified analog signal range.
Source Leakage Current with the Switch OFF
Drain Leakage Current with the Switch OFF
Channel Leakage Current with the Switch ON
Analog Voltage on Terminals D and S
Maximum Input Voltage for Logic “0”

Delay between Applying the Digital Control Input and the Output Switching ON
Delay between Applying the Digital Control Input and the Output Switching OFF
OFF time or ON time measured between the 90% points of both switches, when switching from one
address state to another.
It is a measure of the glitch impulse transferred from the digital input to the analog output during switching.
It is a measure of unwanted signal that is coupled through from one channel to another as a result
of parasitic capacitance.
A Measure of Unwanted Signal Coupling through an OFF Switch
The Frequency at which the Output Is Attenuated by –3 dBs
The Frequency Response of the ON Switch
The Loss due to the On Resistance of the Switch
