TERMINOLOGY
RON
Ohmic resistance between D and S.
ΔRON
Difference between the RON of any two channels.
IS (OFF)
Source leakage current when the switch is off.
ID (OFF)
Drain leakage current when the switch is off.
ID, IS (ON)
Channel leakage current when the switch is on.
VD (VS)
Analog voltage on Terminal D and Terminal S.
CS (OFF)
Channel input capacitance for off condition.
CD (OFF)
Channel output capacitance for off condition.
CD, CS (ON)
On switch capacitance.
CIN
Digital input capacitance.
tON (EN)
Delay time between the 50% and 90% points of the digital input
and switch on condition.
tOFF (EN)
Delay time between the 50% and 90% points of the digital input
and switch off condition.
ADG408/ADG409
tTRANSITION
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.
tOPEN
Off time measured between the 80% point of both switches
when switching from one address state to another.
VINL
Maximum input voltage for Logic 0.
VINH
Minimum input voltage for Logic 1.
IINL (IINH)
Input current of the digital input.
Crosstalk
A measure of unwanted signal that is coupled through from one
channel to another as a result of parasitic capacitance.
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.
IDD
Positive supply current.
ISS
Negative supply current.
