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”
Channel Leakage Current with the Switch “ON”
Maximum Input Voltage for Logic “0”
Minimum Input Voltage for Logic “1”
Input Current of the Digital Input
“OFF” Switch Source Capacitance. Measured with reference to ground.
“ON” Switch Capacitance. Measured with reference to ground.
Digital Input Capacitance
Delay time measured between the 50% and 90% points of the digital inputs and the switch “ON” condition.
Delay time measured between the 50% and 90% points of the digital input and the switch “OFF” condition.
Delay time between the 50% and 90% points of the
EN
digital input and the switch “ON” condition.
Delay time between the 50% and 90% points of the
EN
digital input and the switch “OFF” condition.
“OFF” time measured between the 80% points of both switches when switching from one address state to another.
A measure of the glitch impulse transferred Injection from the digital input to the analog output during switching.
A measure of unwanted signal coupling through an “OFF” switch.
A measure of unwanted signal that is coupled through from one channel to another as a result of parasitic
capacitance.
T he Frequency Response of the “ON” Switch
T he Loss Due to the ON Resistance of the Switch.
