The deviation parameter DVref is defined as the difference between the maximum and minimum values obtained over the full operating ambient temperature range that applies. DVref = Vref max −Vref min DTA = T2 − T1 T2 Ambient Temperature T1 Vref min Vref max The average temperature coefficient of the reference input voltage, aVref is defined as: V ref ppm _C + D V ref V ref @25 _C X106 D T A + D V ref x106 D T A (V ref @25 _C) aVref can be positive or negative depending on whether Vref Min or Vref Max occurs at the lower ambient temperature. (Refer to Figure 6.) Example : DV ref + 8.0 mV and slope is positive, V ref @25 _C + 2.495 V, DT A + 70 _C a V ref + 0.008 x 106 70 (2.495) + 45.8 ppm _C 6. The dynamic impedance ZKA is defined as |ZKA| + D V KA D I K When the device is programmed with two external resistors, R1 and R2, (refer to Figure 2) the total dynamic impedance of the circuit is defined as: |Z KA | [ |Z KA | 1 ) R1 R2 7. NCV431AIDMR2, NCV431AIDR2, NCV431BVDMR2G Tlow = −40°C, Thigh = +125°C. Guaranteed by design. NCV prefix is for automotive and other applications requiring site and change control. |
