TERMINOLOGY
I
Positive supply current.
V

R
Ohmic resistance between D and S.
R
Flatness is the difference between the maximum and minimum
value of on resistance as measured over the specified analog
signal range.
I
Source leakage current with the switch off.
I
Drain leakage current with the switch off.
I
Channel leakage current with the switch on.
V
Maximum input voltage for Logic 0.
V
Minimum input voltage for Logic 1.
I
Input current of the digital input.

C
On switch capacitance. Measured with reference to ground.
C
Digital input capacitance.
t
Delay time between the 50% and the 90% points of the digital
input and switch on condition.
t
Delay time between the 50% and the 90% points of the digital
input and switch off condition.
Charge Injection
A measure of the glitch impulse transferred from the digital
input to the analog output during on-off switching.
Off Isolation
A measure of unwanted signal coupling through an off switch.
−3 dB 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 harmonics amplitude plus noise of a signal to
the fundamental.
PSRR
Power Supply Rejection Ratio. This is a measure of the coupling
of unwanted ac signals on the power supply to the switch output
when the supply is not decoupled.
