Tlow = −40°C for TL431AIP TL431AILP, TL431IP, TL431ILP, TL431BID, TL431BIP, TL431BILP, TL431AIDM, TL431IDM, TL431BIDM; =0°C for TL431ACP, TL431ACLP, TL431CP, TL431CLP, TL431CD, TL431ACD, TL431BCD, TL431BCP, TL431BCLP, TL431CDM, TL431ACDM, TL431BCDM Thigh = +85°C for TL431AIP, TL431AILP, TL431IP, TL431ILP, TL431BID, TL431BIP, TL431BILP, TL431IDM, TL431AIDM, TL431BIDM = +70°C for TL431ACP, TL431ACLP, TL431CP, TL431ACD, TL431BCD, TL431BCP, TL431BCLP, TL431CDM, TL431ACDM, TL431BCDM 2. 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: Vref ppm _C + D Vref Vref @25_C X106 D TA + D Vref x106 D TA (Vref @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 : DVref + 8.0 mV and slope is positive, Vref @25_C + 2.495 V,DTA + 70_C a Vref + 0.008 x 106 70 (2.495) + 45.8 ppm _C 3. The dynamic impedance ZKA is defined as: |ZKA| + D VKA D IK . 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: |ZKA | [ |ZKA| 1 ) R1 R2 |
