Example: Maximum VREF=2.496V at 30oC, minimum VREF =2.492V at 0oC, VREF =2.495V at 25oC, ΔT=70oC αVREF | = [4mV / 2495mV] * 106 / 70oC ≈ 23ppm/oC Because minimum VREF occurs at the lower temperature, the coefficient is positive. * The dynamic impedan ce ZKA is defined as: | ZKA | = ΔVKA / ΔIKA * 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: | ZKA | = Δv / Δi | ≈ ZKA | * ( 1 + R1 / R2)
