TERMINOLOGY
R
ON
Ohmic resistance between D and S.
ΔR
ON
Difference between the R
ON
of any two channels.
R
FLAT(ON)
Flatness is defined as 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 Terminals D and S.
C
S
(Off)
Channel input capacitance for the off condition.
C
D
(Off)
Channel output capacitance for the 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 the switch on condition.
t
OFF
(EN)
Delay time between the 50% and 90% points of the digital input
and the switch off condition.
t
TRANSITION
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% points of the switches
when switching from one address state to another.
V
INL
Maximum input voltage for Logic 0.
V
INH
Minimum input voltage for Logic 1.
I
INL
(I
INH
)
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 Plus Noise (THD + N)
The ratio of the harmonic amplitude plus noise of the signal to
the fundamental.
AC Power Supply Rejection Ratio (ACPSRR)
Measures 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.
