t
TRANS
The delay time between the 50% and 90% points of the digital
input and switch on condition 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.
Off Isolation
A measure of unwanted signal coupling through an off switch.
Crosstalk
A measure of unwanted signal that is coupled through from one
channel to another as a result of parasitic capacitance.
Bandwidth
The frequency at which the output is attenuated by 3 dB.
On Response
The frequency response of the on switch.
Insertion Loss
The loss due to the on resistance of the switch.
THD + N
The ratio of the harmonic amplitude plus noise of the signal to
the fundamental.
