Deviation of reference input voltage, VDEV, is defined as the maximum variation of the reference over the full temperature range.
ISSUED DATE :2004/10/22 REVISED DATE : The average temperature coefficient of the reference input voltage Ø VREF is defined as: Where: T2 – T1 = full temperature change. Ø VREF can be positive or negative depending on whether the slope is positive or negative. Note2. The dynamic output impedance, RZ, is defined as: When the device is programmed with two external resistors R1 and R2 (see figure 2.), the dynamic output impedance of the overall circuit, is defined as: Test Circuits Typical Performance Characteristics
