t
ON
Delay time between the 50% and the 90% points of the digital
input and switch on condition.
t
OFF
Delay time between the 50% and the 90% points of the digital
input and switch off condition.
t
BBM
On or off time measured between the 80% points of both
switches when switching from one to another.
Charge Injection
A measure of the glitch impulse transferred from the digital
input to the analog output during on-off 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.
−3 dB 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 amplitudes plus noise of a signal, to
the fundamental.
