TERMINOLOGY
R
Ohmic resistance between D and S.
R
Flatness is defined as the difference between the maximum and
minimum value of on resistance as measured.
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
Analog voltage on Terminal D and Terminal S.
C
Off switch source capacitance. Measured with reference to
ground.
C
Off switch drain capacitance. Measured with reference to
ground.

C
On switch capacitance. Measured with reference to ground.
t
Delay time between the 50% and the 90% points of the digital
input and switch on condition. See Figure 14.
t
Delay time between the 50% and the 90% points of the digital
input and switch off condition.
Off Isolation
A measure of unwanted signal coupling through an off switch.
Charge Injection
A measure of the glitch impulse transferred from the digital
input to the analog output during on-off switching.
Bandwidth
The frequency at which the output is attenuated by −3 dB.
On Response
The frequency response of the on switch.
On Loss
The voltage drop across the on switch as how many dBs the
signal is away from 0 dB at very low frequencies. See Figure 10.
