TS432/A/B 3-7 2003/12 rev. A Note 4. Deviation of reference input voltage, VDEV, is defined as the maximum deviation of the reference over the full temperature range. The average temperature coefficient of the reference input voltage αVref is defined as: | αVref | = [ VDEV / Vref(25) ] * 106 / T2 – T1…………………….. (PPM/ oC) Where: T2-T1 = full temperature change. αVref can be positive or negative depending on whether the slope is positive or negative. Note 5. The dynamic output impedance, Rz, is defined as: | Zka | = ∆Vka / ∆Ika When the device is programmed with two external resistors R1and R2 (see Figure 2). The dynamic output impedance of the overall circuit, is defined as : Test Circuits
