NOTES
1Typical values represent average readings taken at room temperature.
2Conditions: 2.4 V < VIN < 5.5 V, 0 µA < IOUT < 10 µA, –40°C < TA < +85°C.
3Power supply ripple rejection measurement applies to a changing input voltage (VIN) waveform with a nominal 3.6 V baseline that drops to a 3 V value for
380 µs at a 4.6 ms repetition rate.

NOTES
1Stresses above those listed under Absolute Maximum Ratings may cause permanent
damage to the device. This is a stress rating only and 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.
2 Absolute Maximum Ratings apply at 25°C, unless otherwise noted.

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 the ADR280
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.
