The tolerance values, across the temperature range, are calculated as: ±Vk25°C x {tolerance25°C+[(ppmmax /°C) x (∆T)]}. Example: TLVH431A ∆Vk = ±1.24 x (0.5% + 100 ppm/°C x 165 °C) = ±1.24 x (0.5%+1.65%)= ±1.24 x 2.15% = ± 26.7 mV. 2. The dynamic impedance is defined as ZKA=∆VKA/∆Ik. Note: Limits are 100% production tested at 25 °C. Limits over the temperature range are guaranteed through correlation and by design.
