TERMINOLOGY
R
ON
Ohmic resistance between Term inal D and Terminal S.
∆R
ON
The difference between the R
ON
of any two channels.
R
FLAT(ON)
The difference between the maximum and minimum value of
on resistance as measured.
I
S
(Off)
Source leakage current when the switch is off.
I
D
(Off)
Drain leakage current when the switch is off.
I
D
, I
S
(On)
Channel leakage current when the switch is on.
V
D
(V
S
)
Analog voltage on Terminal D and Terminal S.
C
S
(Off)
Channel input capacitance for off condition.
C
D
(Off)
Channel output capacitance for off condition.
C
D
, C
S
(On)
On switch capacitance.
C
IN
Digital input capacitance.
t
ON
(
EN
)
Delay time between the 50% and 90% points of the digital input
and switch on condition.
t
OFF
(
EN
)
Delay time between the 50% and 90% points of the digital input
and switch off condition.
t
TRANS
Delay time between the 50% and 90% points of the digital
inputs and the switch on condition when switching from one
address state to another.
t
BBM
Off time measured between the 80% point of both switches
when switching from one address state to another.
V
IL
Maximum input voltage for Logic 0.
V
IH
Minimum input voltage for Logic 1.
I
IL
(I
IH
)
Input current of the digital input.
I
DD
Positive supply current.
I
SS
Negative supply current.
Off Isolation
A measure of unwanted signal coupling through an off channel.
Charge Injection
A measure of the glitch impulse transferred from the digital
input to the analog output during switching.
Bandwidth
The frequency at which the output is attenuated by 3 dB.
On Response
The frequency response of the on switch.
Total Harmonic Distortion + Noise (THD + N)
The ratio of the harmonic amplitude plus noise of the signal to
the fundamental.
AC Power Supply Rejection Ratio (ACPSRR)
A measure of the ability of a device to avoid coupling noise
and spurious signals that appear on the supply voltage pin
to the output of the switch. The dc voltage on the device is
modulated by a sine wave of 0.62 V p-p. The ratio of the
amplitude of signal on the output to the amplitude of the
modulation is the ACPSRR.
