If the analog inputs are driven from alternative V
DD
and V
SS
supply circuitry,
Schottky diodes should be placed in series with the AD7327 V
DD
and V
SS
supplies. See Power Supply Configuration section.

Transient currents of up to 100 mA do not cause SCR latch-up.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
