1

If the analog inputs are driven from alternative VDD and VSS supply circuitry,

Schottky diodes should be placed in series with the AD7327 VDD and VSS

supplies. See Power Supply Configuration section.

2

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.
