ADG704
–4–
REV. A
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADG704 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.

Flatness is defined as the difference between
the maximum and minimum value of on resis-
tance as measured over the specified analog
signal range.

t
ON
Delay between applying the digital control
input and the output switching on. See Test
Circuit 4.
t
OFF
Delay between applying the digital control
input and the output switching off.
t
D
“OFF” time or “ON” time measured between
the 90% points of both switches, when switching
from one address state to another. See Test
Circuit 5.
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.
Bandwidth The frequency at which the output is attenu-
ated by –3 dBs.
On Response The frequency response of the “ON” switch.
On Loss The voltage drop across the “ON” switch,
seen on the On Response vs. Frequency plot
as how many dBs the signal is away from 0 dB
at very low frequencies.

NOTES
1
Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability. Only one absolute
maximum rating may be applied at any one time.
2
Overvoltages at IN, S or D will be clamped by internal diodes. Current should be
limited to the maximum ratings given.
