ADG781/ADG782/ADG783

–5–

Most positive power supply potential.

GND

Ground (0 V) reference.

S

Source terminal. May be an input or output.

D

Drain terminal. May be an input or output.

IN

Logic control input.

Ohmic resistance between D and S.

On-resistance match between any two chan-

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 terminals D, S.

“OFF” switch source capacitance.

“OFF” switch drain capacitance.

“ON” switch capacitance.

Delay between applying the digital control

input and the output switching on.

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 (ADG783 only).

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” switch.

Charge

A measure of the glitch impulse transferred

Injection

from the digital input to the analog output

during switching.

On Response

The frequency response of the “ON” switch.

On Loss

The loss due to the on resistance of the switch.
