7 / 20 page ADR121/ADR125/ADR127 Rev. 0 | Page 7 of 20 TERMINOLOGY Temperature Coefficient The change of output voltage with respect to operating temperature change normalized by the output voltage at 25°C. This parameter is expressed in ppm/°C and can be determined by [] () ( ) () () 6 1 2 1 2 10 C 25 C ppm/ × − × ° − = ° T T V T V T V TCV O O O O where: VO(25°C) = VO at 25°C. VO(T1) = VO at Temperature 1. VO(T2) = VO at Temperature 2. Line Regulation The change in the output due to a specified change in input voltage. This parameter accounts for the effects of self-heating. Line regulation is expressed in either percent per volt, parts- per-million per volt, or microvolts per voltage changes in input voltage. Load Regulation The change in output voltage due to a specified change in load current. This parameter accounts for the effects of self-heating. Load regulation is expressed in either microvolts per milliam- pere, parts-per-million per milliampere, or ohms of dc output resistance. Long-Term Stability Typical shift of output voltage at 25°C on a sample of parts subjected to a test of 1000 hours at 25°C. ( ) ( ) [] () () () 6 1 1 10 ppm × − = Δ − = Δ O O O O O O O O O O t V t V t V V t V t V V where: VO(t0) = VO at 25°C at Time 0. VO(t1) = VO at 25°C after 1000 hours operating at 25°C. Thermal Hysteresis The change of output voltage after the device is cycled through temperatures from +25°C to −40°C to +125°C and back to +25°C. This is a typical value from a sample of parts put through such a cycle. where: VO (25°C) = VO at 25°C. VOTC = VO at 25°C after temperature cycle at +25°C to −40°C to +125°C and back to +25°C. |
