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 90% 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 on-off switching.
Off Isolation
A measure of an unwanted signal coupling through an
off switch.
Crosstalk
A measure of an 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 attenuation between the input and output ports of the
switch when the switch is in the on condition and is due to
the on resistance of the switch.
