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.

Charge Injection

It is a measure of the glitch impulse transferred from the digital input to the analog output during switching.

Crosstalk

It is a measure of unwanted signal that is coupled through from one channel to another as a result

of parasitic capacitance.

Off Isolation

A Measure of Unwanted Signal Coupling through an OFF Switch
