Guaranteed but not tested. 13. The deviation parameters DVref and DIref are defined as the difference between the maximum value and minimum value obtained over the full operating ambient temperature range that applied. Vref Max Vref Min T1 T2 Ambient Temperature DVref = Vref Max − Vref Min DTA = T2 − T1 The average temperature coefficient of the reference input voltage, aVref is defined as: αV ref ppm °C + ( DV ref ) V ref (T A + 25 °C) 106 DT A aVref can be positive or negative depending on whether Vref Min or Vref Max occurs at the lower ambient temperature, refer to Figure 8. Example: DVref = 7.2 mV and the slope is positive, Example: Vref @ 25°C = 1.241 V Example: DTA = 125°C αV ref ppm °C + 0.0072 1.241 125 + 46 ppm °C 106 14. The dynamic impedance ZKA is defined as: ⏐Z KA⏐ + DV KA DI K When the device is operating with two external resistors, R1 and R2, (refer to Figure 4) the total dynamic impedance of the circuit is given by: ⏐ZKA′⏐ + ⏐ZKA⏐ 1 ) R1 R2 Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product performance may not be indicated by the Electrical Characteristics if operated under different conditions. |
