VOLT AGE VARIAT ION VS. T E MPE RAT URE AND LINE
Some confusion exists in the area of defining and specifying ref-
erence voltage error over temperature. Historically, references
are characterized using a maximum deviation per degree Centi-
grade; i.e., 10 ppm/
°
C. However, because of the inconsistent
nonlinearities in Zener references (butterfly or “S” type charac-
teristics), most manufacturers use a maximum limit error band
approach to characterize their references. T his technique mea-
sures the output voltage at 3 to 5 different temperatures and
guarantees that the output voltage deviation will fall within the
guaranteed error band at these discrete temperatures. T his ap-
proach, of course, makes no mention or guarantee of perfor-
mance at any other temperature within the operating
temperature range of the device.
T he consistent Voltage vs. T emperature performance of a typi-
cal AD1403 is shown in Figure 6. Note that the characteristic is
quasi-parabolic, not the possible “S” type characteristics of clas-
sical Zener references. T his parabolic characteristic permits a
maximum output deviation specification over the device’s full
operating temperature range, rather than just at 3 to 5 discrete
temperatures.
