3 / 4 page AD1403/AD1403A REV. A –3– Figure 3. Typical Change in VOUT vs. VIN (Normalized to VOUT @ VlN = 15 V @ TC = 25°C) Figure 4. Change in Output Voltage vs. Load Current (Normalized to VOUT @ VIN = 15 V, lOUT = 0 mA) Figure 5. Quiescent Current vs. Temperature (VIN = 15 V, IOUT = 0 mA) Typical Performance Curves– Figure 6. Change in VOUT vs. Temperature (Normalized to VOUT @ VIN = 15 V) Figure 7. Change in VOUT vs. Temperature (Normalized to VOUT @ VlN = 15 V, IOUT = 0 mA) VOLTAGE VARIATION VS. TEMPERATURE 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. This 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. This ap- proach, of course, makes no mention or guarantee of perfor- mance at any other temperature within the operating temperature range of the device. The consistent Voltage vs. Temperature 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. This 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. |
