Deviation of reference input voltage, VDEV, is defined as the maximum variatio of the reference over the full temperature range. The average temperature coefficient of the reference input voltage α VREF is defined as: Where: T2-T1 = full temperature change. α VREF can be positive or negative depending on whether the slope is positive or negative. Note 2. The dynamic output impedance, RZ, is defined as: |
