TERMINOLOGY
I
Positive supply current.
V
Analog voltage on Terminal D and Terminal S.
R
Ohmic resistance between Terminal D and Terminal S.
R
The difference between the maximum and minimum values of
on resistance as measured on the switch.
ΔR
On resistance match between any two channels.
I
Source leakage current with the switch off.
I
Drain leakage current with the switch off.
I
Channel leakage current with the switch on.
V
Maximum input voltage for Logic 0.
V
Minimum input voltage for Logic 1.
I
Input current of the digital input.
C

C
On switch capacitance. Measured with reference to ground.
C
Digital input capacitance.
t
Delay time between the 50% and 90% points of the digital input
and switch on condition.
t
Delay time between the 50% and 90% points of the digital input
and switch off condition.
t
On or off time measured between the 80% points of both
switches when switching from one to another.
Charge Injection
Measure of the glitch impulse transferred from the digital input
to the analog output during on/off switching.
Off Isolation
Measure of unwanted signal coupling through an off switch.
Crosstalk
Measure of unwanted signal that is coupled from one channel to
another as a result of parasitic capacitance.
−3 dB Bandwidth
Frequency at which the output is attenuated by 3 dB.
On Response
Frequency response of the on switch.
Insertion Loss
The loss due to the on resistance of the switch.
THD + N
Ratio of the harmonics amplitude plus noise of a signal to the
fundamental.
