1 All voltages are relative to their respective ground.
2 Input-to-output voltage is defined as GNDA − GND1 or GNDB − GND1.
3 Output differential voltage is defined as GNDA − GNDB.
4 Refers to common-mode transients across any insulation barrier. Common-
mode transients exceeding the Absolute Maximum Ratings can cause latch-
up or permanent damage.
ADuM1230
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 listed in the operational sections
of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
Ambient temperature = 25°C, unless otherwise noted.

Notes
Output returns to input state within 1 μs of VDDI power restoration.
ESD 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 this product 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.
