THERMAL CHARACTERISTICS
8-Pin Plastic DIP Package
8-Pin Plastic SO Package
Absolute maximum ratings are those beyond which the safety of the device cannot be guaranfeed.
All currents into device pins are positive; all currents out ot device pins are negative. All voltages are referenced to device ground unless otherwise specified.
All typicals are given for Vcc = 5V and Tp = 25°C.
The 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.
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.
