ADG4612/ADG4613
BIPOLAR OPERATION AND SINGLE-SUPPLY
OPERATION
The ADG4612/ADG4613 have a maximum operational range
from V
to drain, V
the signal range can exceed the power supply rails, but the voltage
between the most negative voltage on the device (V
should be within 16 V of the most positive voltage (V
or V
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.

Positive Fault Condition
If the analog input exceeds V
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
an overvoltage of up to 16 V. If V
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
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
that the downstream circuitry can handle this signal level. Also,
the user should ensure the voltage between the most negative
