TERMINOLOGY
V
DD
Most positive power supply potential.
V
SS
Most negative power supply potential.
I
DD
Positive supply current.
I
SS
Negative supply current.
GND
Ground (0 V) reference.
S
Source terminal. Can be an input or output.
D
Drain terminal. Can be an input or output.
A
X
Logic control input.
EN
Active low digital input. When
EN
is high, the device is disabled
and all switches are off. When
EN
is low, the Ax logic inputs
determine the on switches.

ΔR
ON
On-resistance match between any two channels, that is,
R
ONMAX
− R
ONMIN
.
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

C
S(OFF)
Off switch source capacitance. Measured with reference to
ground.
C
D(OFF)

t
ON
(
EN
)
Delay between applying the digital control input and the output
switching on (see Figure 26).
t
OFF
(
EN
)
Delay between applying the digital control input and the output
switching off (see Figure 26).
t
BBM
On time, measured between 80% points of both switches when
switching from one address state to another.
Charge Injection
A measure of the glitch impulse transferred from the digital
input to the analog output during switching.
Off Isolation
A measure of unwanted signal coupling through an off switch.
Crosstalk
A measure of unwanted signal that is coupled through from one
channel to another as a result of parasitic capacitance.
Bandwidth
The frequency at which the output is attenuated by 3 dB.
On Response
The frequency response of the on switch.
Insertion Loss
The loss due to the on resistance of the switch.
