Data Sheet AD1582/AD1583/AD1584/AD1585 TERMINOLOGY Temperature Coefficient (TCV Thermal Hysteresis (VO_HYS) O)
The change of output voltage over the operating temperature The change of output voltage after the device is cycled through change and normalized by the output voltage at 25°C, expressed temperatures from +25°C to −40°C to +85°C and back to +25°C. in ppm/°C. The equation follows This is a typical value from a sample of parts put through such a cycle TCV [ V T −V T V = ° − _ V (25 C) O ppm/ C ° ] ( ) ( ) O 2 O 1 6 = × V V ( °C)×(T −T ) 10 O HYS O O _TC O 25 2 1 V ° O C − where: V [ V O HYS ppm] (25 ) O_TC 6 = × _ 10 V V ( O 25°C) O (25°C) = VO at 25°C. VO (T1) = VO at Temperature 1. where: VO (T2) = VO at Temperature 2. VO (25°C) = VO at 25°C.
Line Regulation (ΔVO/ΔVIN) Definition
VO_TC = VO at 25°C after temperature cycle at +25°C to −40°C to The change in output voltage due to a specified change in input +85°C and back to +25°C. voltage. It includes the effects of self-heating. Line regulation is

specified temperature range. 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 ohms of dc output resistance.
Long-Term Stability (ΔVO)
Typical shift of output voltage at 25°C on a sample of parts subjected to an operation life test of 1000 hours at 125°C. V ∆ = V (t )−V (t ) O O 0 O 1 V t V t ∆V [ − O ppm] ( ) ( ) O 0 O 1 6 = V (t ) ×10 O 0 where: VO (t0) = VO at 25°C at Time 0. VO (t1) = VO at 25°C after 1000 hours of operation at 125°C. Rev.
