TERMINOLOGY
I
The positive supply current.
I
The negative supply current.
V
The analog voltage on Terminal D and Terminal S.
R

R
Flatness is defined as the difference between the maximum and
minimum value of on resistance as measured over the specified
analog signal range.
I
The source leakage current with the switch off.
I
The drain leakage current with the switch off.
I
The channel leakage current with the switch on.
V
The maximum input voltage for Logic 0.
V
The minimum input voltage for Logic 1.
I
The input current of the digital input.
C
The off switch source capacitance, measured with reference to
ground.
C
The off switch drain capacitance, measured with reference to
ground.

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
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
Off time measured between the 80% point 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.
THD + N
The ratio of the harmonic amplitude plus noise of the signal to
the fundamental.
ACPSRR (AC Power Supply Rejection Ratio)
Measures the ability of a part 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.
