ADG708/ADG709

–6–

REV. 0

Most positive power supply potential.

Most negative power supply in a dual supply

application. In single supply applications, this

should be tied to ground at the device.

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.

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. Measured

with reference to ground.

“OFF” switch drain capacitance. Measured

with reference to ground.

“ON” switch capacitance. Measured with

reference to ground.

Digital Input Capacitance.

Delay time measured between the 50% and 90%

points of the digital inputs and the switch “ON”

condition when switching from one address state

to another.

TERMINOLOGY

Delay time between the 50% and 90% points

of the EN digital input and the switch “ON”

condition.

Delay time between the 50% and 90% points

of the EN digital input and the switch “OFF”

condition.

“OFF” time measured between the 80% points

of both switches when switching from one address

state to another.

Off Isolation

A measure of unwanted signal coupling through

an “OFF” switch.

Crosstalk

A measure of unwanted signal which is coupled

through from one channel to another as a result

of parasitic capacitance.

Charge

A measure of the glitch impulse transferred from

Injection

the digital input to the analog output during

switching.

Bandwidth

The frequency at which the output is attenuated

by 3 dBs.

On Response The frequency response of the “ON” switch.

On Loss

The loss due to the ON resistance of the switch.

Maximum input voltage for Logic “0.”

Minimum input voltage for Logic “1.”

Input current of the digital input.

Positive Supply Current.

Negative Supply Current.
