TERMINOLOGY

Ohmic resistance between D and S.

Flatness is defined as the difference between the maximum and

minimum value of on resistance, as measured over the specified

analog signal range.

Source leakage current with the switch off.

Drain leakage current with the switch off.

Channel leakage current with the switch on.

Analog voltage on Terminal D and Terminal S.

Off switch source capacitance.

Off switch drain capacitance.

On switch capacitance.

Delay between applying the digital control input and the output

switching on. See Figure 19.

Delay between applying the digital control input and the output

switching off.

Off time or on time measured between the 90% points of both

switches, when switching from one address state to another. See

Figure 20.

Crosstalk

A measure of unwanted signal coupled through from one

channel to another as a result of parasitic capacitance.

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 switching.
