Example: Maximum V REF =2.496V at 30 oC, minimum VREF =2.492V at 0oC, VREF =2.495V at 25 oC, ∆T=70 oC αVREF | = [4mV / 2495mV] * 10 6 / 70 oC ≈ 23ppm/ oC Because minimum VREF occurs at the lower temperature, the coefficient is positive. * The dynamic impedance Z KA is defined as: | Z KA | = ∆VKA / ∆IKA * When the device operating with two external resistors, R1 and R2, (refer to Figure 2) the total dynamic impedance of the circuit is given by: | Z
