Notes:
6. Deviation of reference input voltage, V DEV , is defined as the maximum variation of the reference over the full temperature range.
The average temperature coefficient of the reference input voltage α V REF is defined as:
α V REF =
(

Where:
T2 – T1 = full temperature change.
α V REF can be positive or negative depending on whether the slope is positive or negative.
Notes:
7. The dynamic output impedance, R Z , is defined as:
Z KA =
Δ V KA
Δ I KA
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:
