t
ON
Delay between applying the digital control input and the output
switching on.
t
OFF
Delay between applying the digital control input and the output
switching off.
t
OPEN
Break-before-make delay when switches are configured as a
multiplexer.
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.
