11 / 16 page ADR130 Rev. 0 | Page 11 of 16 TERMINOLOGY Temperature Coefficient Temperature coefficient is the change of output voltage with respect to the operating temperature change normalized by the output voltage at 25°C. This parameter is expressed in ppm/°C and is determined by [] ( ) ( ) () () 6 10 C 25 C ppm/ × − × ° − = ° 1 2 O 1 O 2 O O T T V T V T V TCV where: VO (25°C) = VO at 25°C. VO(T1) = VO at Temperature 1. VO (T2) = VO at Temperature 2. Line Regulation Line regulation is 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 %/V, ppm/V, or μV/ΔVIN. Load Regulation Load regulation is 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 mV/mA, ppm/mA, or dc output resistance (Ω). Long-Term Stability Long-term stability is the typical shift of output voltage at 25°C on a sample of parts subjected to a test of 1000 hours at 25°C. ( ) ( ) 1 O 0 O O t V t V V − = Δ [] ( ) () () 6 10 ppm × − = Δ 0 O 1 O 0 O O t 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 Thermal hysteresis is the change of output voltage after the device is cycled through temperatures from +25°C to −40°C to +125°C, then 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 from +25°C to −40°C to +125°C, then back to +25°C. |
