BIPOLAR OPERATION AND SINGLE-SUPPLY
OPERATION
The ADG4612/ADG4613 have a maximum operational range
from V
DD
to V
SS
of 16 V. The maximum signal range from source
to drain, V
S
to V
D
, is also 16 V. During operation of the device,
the signal range can exceed the power supply rails, but the voltage
between the most negative voltage on the device (V
S
,V
D
or V
SS
)
should be within 16 V of the most positive voltage (V
S
, V
D
, INx,
or V
DD
). These voltage ratings should be adhered to at all times
for guaranteed functionality. See Table 5 for guaranteed supply
ranges. Signal ranges and power supply ranges exceeding 16 V
may affect the long-term reliability of the device.
The ground pin must always be connected to the GND
potential to ensure proper functionality in isolation and
normal operation mode.
The minimum V
DD
voltage that the part is guaranteed operational
is 2.7 V. The maximum recommended V
DD
voltage is 16 V.
The minimum supply voltage recommended on V
SS
is −5.5 V,
and the maximum voltage allowable on V
SS
is 0 V. Therefore,
given that the V
DD
to V
SS
range is 16 V maximum when, V
SS
=
−5.5 V, the V
DD
= +10.5 V maximum.
Positive Fault Condition
If the analog input exceeds V
DD
by a threshold voltage, V
T
, then
the switch turns off and is in isolation mode. The part can handle a
fault of up to 16 V, referenced to the most negative signal. For
example, if V
DD
= 5 V, V
SS
= 0 V, then the switch protects against
an overvoltage of up to 16 V. If V
SS
= −5 V and V
DD
= +5 V, then
the switch protects against an overvoltage of up to +11 V.
Negative Fault Condition; Negative Signal Handling
The ADG4612/ADG4613 are not damaged if the analog inputs
exceed the negative supply, V
SS
. If the switch is in the off condition,
the switch blocks a signal up to −5.5 V. If the switch is in the on
condition, the switch remains on, and the negative signal is passed
to the output; therefore, the ADG4612/ADG4613 can pass a
negative signal up to −5.5 V with V
SS
= 0 V. The user must ensure
that the downstream circuitry can handle this signal level. Also,
the user should ensure the voltage between the most negative
voltage on the device (V
S
,V
D
or V
SS
) is within 16 V of the most
positive voltage (V
S
, V
D
, INx, or V
DD
).
