from one address state to another.
t
BBM
“OFF” time or “ON” time measured between the 80% points of both switches, when switching from one address
state to another.
Charge Injection A measure of the glitch impulse transferred from the digital input to the analog output during switching.
Crosstalk 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 “On” switch.
Bandwidth Frequency Response of the “On” Switch
Insertion Loss Loss Due to the On Resistance of the Switch
