Crosstalk
A measure of unwanted signal which 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.
Charge Injection
A measure of the glitch impulse transferred from the digital
input to the analog output during switching.
