All voltages are referenced to device ground unless otherwise specified. 3All typicals are given for Vcc = 5V and Tp = 25°C. 4The ADM1487 is not tested and is not quality-assurance sampled at -40°C and at 85°C. These specifications are guaranteed by design, correlation, andlor inference from 0°C, 25°C and/or 70°C tests.

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.
