D ABSOLUTE MAXIMUM RATINGS 1 Internal Power Dissipation 2 Specified Temperature Range AD1582RT/AD1583RT/, Lead Temperature, Soldering NOTES 1Stresses above those listed under Absolute Maximum Ratings may cause perma- nent 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. 2Specification is for device in free air at 25 °C: SOT-23 package: θJA = 300°C/W. 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 AD1582/AD1583/AD1584/AD1585 feature 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. PACKAGE BRANDING INFORMATION Four fields identify the device:

• First field, product identifier, for example, a “2/3/4/5” identifies the generic as AD1582/AD1583/AD1584/AD1585
• Second field, device grade, which can be “A,” “B,” or “C”
• Third field, calendar year of processing, “7” for 1997..., “A” for 2001...
• Fourth field, two-week window within the calendar year, for example, letters A–Z to represent a two-week window starting with “A” for the first two weeks of January.

AD1582/AD1583/AD1584/AD1585 –7–REV. D PARAMETER DEFINITIONS Temperature Coefficient (TCV O) The change of output voltage over the operating temperature change and normalized by the output voltage at 25 /H11034C, expressed in ppm//H11034C. The equation follows: TCV VT VT VT T O O2 O1 O2 1 °() ×−() ×25 106 where: VO(25/H11034C) = VO at 25/H11034C VO(T1) = VO at temperature 1 VO(T2) = VO at temperature 2 Line Regulation ( ∆VO/∆VIN) The change in output voltage due to a specified change in input voltage. It includes the effects of self-heating. Line regulation is expressed in either percent per volt, parts per million per volt, or microvolts per volt change in input voltage. Load Regulation ( ∆VO/∆ILOAD) The change in output voltage due to a specified change in load current. It includes the effects of self-heating. Load regulation is expressed in either microvolts per milliampere, parts per million per milliampere, or Ω of dc output resistance. Long-Term Stability ( ∆VO) Typical shift of output voltage at 25 /H11034C on a sample of parts subjected to an operation life test of 1000 hours at 125 /H11034C: VV t V t V Vt Vt Vt OO 0 O 1 O O0 O1 = () − () [] = () − () ×ppm 10 6 where: VO(t0) = VO at 25/H11034C at time 0 VO(t1) = VO at 25/H11034C after 1000 hours operation at 125 /H11034C Thermal Hysteresis (V O_HYS) The change of output voltage after the device is cycled through temperatures from +25/H11034C to –40/H11034C to +85°C and back to +25/H11034C. This is a typical value from a sample of parts put through such a cycle: VV V V VV V O_HYS O O_TC O_HYS OO _ T C O =° () − [] = °() − °() 25 106 C ppm C Cwhere: VO(25/H11034C) = VO at 25/H11034C VO_TC = VO at 25/H11034C after temperature cycle at +25 /H11034C to –40/H11034C to +85/H11034C and back to +25/H11034C Operating Temperature The temperature extremes at which the device can still function.
