Preliminary Technical Data
TERMINOLOGY
IDD
The positive supply current.
ISS
The negative supply current.
VD (VS)
The analog voltage on Terminals D and S.
RON
The ohmic resistance between D and S.
RFLAT(ON)
Flatness is defined as the difference between the maximum and
minimum value of on resistance, as measured over the specified
analog signal range.
IS (Off)
The source leakage current with the switch off.
ID (Off)
The drain leakage current with the switch off.
ID, IS (On)
The channel leakage current with the switch on.
VINL
The maximum input voltage for Logic 0.
VINH
The minimum input voltage for Logic 1.
IINL (IINH)
The input current of the digital input.
CS (Off)
The off switch source capacitance, which is measured with
reference to ground.
CD (Off)
The off switch drain capacitance, which is measured with
reference to ground.

CD, CS (On)
The on switch capacitance, which is measured with reference to
ground.
CIN
The digital input capacitance.
tON (EN)
The delay between applying the digital control input and the
output switching on. See Figure 24, Test Circuit 4.
tOFF (EN)
The delay between applying the digital control input and the
output switching off.
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.
tTRANS
The delay time between the 50% and 90% points of the digital
input and switch on condition when switching from one
address state to another.
