Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Rev. B | Page 4 of 8

Historically, references Figure 3. Extrapolated Variation of Base-Emitter Voltage with Temperature are characterized using a maximum deviation per degree (IEαT), and Required Compensation, Shown for Two Different Devices Centigrade; i.e., 10 ppm/°C. However, because of the inconsistent nonlinearities in Zener references (butterfly or S type characteristics), most manufacturers use a maximum limit error band approach to characterize their references. This technique measures 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 approach, of course, makes no mention or guarantee of performance at any other temperature within the operating temperature range of the device. Rev. B | Page 5 of 8

AD580 The consistent voltage versus temperature performance of a 1mV typical AD580 is shown in Figure 7. Note that the characteristic is quasi-parabolic, not the possible S type characteristics of classical Zener references. This parabolic characteristic permits E a maximum output deviation specification over the device’s full OIS100µV N operating temperature range, rather than just at 3 to 5 discrete K A temperatures.
