Charge Injection
Charge injection is a measure of the glitch impulse transferred
from the digital input to the analog output during switching.
Off Isolation
Off isolation is a measure of the unwanted signal coupling
through an off switch.
Channel-to-Channel Crosstalk
Crosstalk is a measure of unwanted signal that is coupled
through from one channel to another as a result of parasitic
capacitance.
Insertion Loss
Insertion loss is the loss due to the on resistance of the switch.
