TERMINOLOGY
R
ON
Ohmic resistance between D and S.
ΔR
ON
On resistance match between any two channels, such as: R
ON
max − R
ON
min.
R
FLAT(ON)
Flatness is defined as the difference between the maximum and
minimum value of on resistance as measured over the specified
analog signal range.
I
S
(Off)
Source leakage current with the switch off.
I
D
, I
S
(On)
Channel leakage current with the switch on.
V
D
(V
S
)
Analog voltage on Terminals D and S.
C
S
(Off)
Off switch source capacitance.
C
D
, C
S
(On)
On switch capacitance.
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
D
Off time or on time measured between the 90% points of both
switches, when switching from one address state to another.
Crosstalk
A measure of unwanted signal that 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.
Bandwidth
The frequency at which the output is attenuated by −3 dBs.
On Response
The frequency response of the on switch.
Insertion Loss
Loss due to on resistance of the switch.
